We will get back to you and arrange for you to get a trap from one of us


Seems the cat-trap you mentioned used some years ago, belonged to AVA.
I hope AVA had discontinued using those inhumane cat-traps with hooks, as proposed by Animal Lovers League few years ago.

Here is an article pertaining the cat-traps with hooks, from Animal Lovers League newsletter - Bulletin dated June to December 2002 :

Cat traps

A case was reported to us about a stray cat caught in a cat-trap from the AVA.
While the cat was reaching out for a piece of meat (used as bait) attached on the cat trap by a hook, it got its cheek caught in the hook instead. None of the diners at the coffee shop called the AVA or SPCA.
As it struggled to free itself, the tear on the cheek worsens. It was nearly 12 hours later that the case was reported and AVA collected it and put it to sleep still hooked by the cheek, bleeding and screaming. Thank God for that, as it would have caused more pain to the struggling cat if they tried to unhook it first. We received the call after AVA had collected it.

On this note, we therefore advise that for those who need to use cat-traps, please refrain from using the old traps with the hook. We are now proposing to AVA to discontinue the use of such traps.

The above article is taken from Animal Lovers League newsletter - Bulletin dated June to December 2002.

Hi Blue Mistz,

AVA had modified the sharp hooks in their old cat traps.
Instead of sharp, pointed hooks, the hooks are now blunt, and would not injured trapped cats.

AVA also having new type of no hook cat traps similar to Cat Welfare Society cat traps. I understand people wanting to loan cat traps from AVA, are given a choice of what type of cat traps they prefer - subject to availability.

A friend who was at AVA recently to renew a dog's licence, saw a couple putting a cat trap into the boot of their BMW. Presumably it was another intolerance of the presence of cats into their "precious property".

AVA replies

We got a reply from AVA about a few things we enquired about.

First of all, they DID send out letters to the town councils to express MND and AVA's support for sterilisation. They felt that sterilisation and killing the cats were both necessary components of a community cat programme.

The AVA also encouraged the town councils to work with caregivers and mentioned that the AVA was prepared to give a sterilisation subsidy and whom to call for more information. This letter was apparently sent out to all the town councils in April!

I'm certainly delighted to hear that the AVA is willing to sponsor sterilisations, and perhaps even more importantly, to support sterilisation AND working with caregivers. They've asked the town council to approach them for more information on the programme and for further information on the subsidies. Now the ball is really in the town council's court. Caregivers can (and should) speak with their TCs about getting this programme on the road!

Secondly, the AVA felt that it would be a breach of confidentiality to give out the details of complainants in private estates whom borrow cat traps. What we asked was that if someone borrows a cat trap, that they sign a form saying that they are willing to speak with caregivers if there is anyone there so I'll write to clarify this.

Thirdly, they mentioned that they would be willing to consider handing out the brochure on alternatives to killing cats for people who borrow cat traps. However, they wanted CWS to have a brochure that mentions alternatives to trapping AND killing.

We're clearly not going to do that because we're trying to provide alternatives to having the cats killed. Clearly also if someone borrows a cat trap, they KNOW about the killing - plus it's not a solution to solving the nuisances, so we're going to write about that too.

4. My cat can appreciate my wife's cooking aromas

Sep 23, 2008

"Doctor, my cat can now twitch his nose, life his head and appreciate the smells of my wife's curry in the kitchen," the owner suddenly remarked at the review of his cat's urinary problem after 2 weeks of treatment. I was surprised to hear him saying that his cat had lost his sense of smell for some weeks.

2 weeks ago, his cat had a strong urine smell in his belly. A white hairless skin patch full of urine stains in this belly area. What was the cause? The male cat pees away from his backside and not towards his belly. Even if he was incontinent or had a urinary tract infection (UTI), his urine would dribble onto his backside and anal area. But only his belly which was far away was affected.

This cat had given the owner some headaches. One day, he jumped at a bird near the window sill and fell four storeys down. Fortunately he did not suffer any internal injuries and was alive.

"As a prevention, I close all the windows nowadays when my family is not supervising this cat," the owner said.

"Will it not be stuffy when you don't let air into the apartment?" I asked.

"Yes. But this cat may leap at another bird at the window and crash," the owner said.

"The cat has 9 lives," I said. "He has used up one. But seriously, why don't you buy wire-mesh to cover the window opening?"

The owner was not so keen at this idea, but some cat owners do that, to prevent the cat running out of the main grille door and jumping off the windows.

Now, back to his cat's urinary problems. On instant diagnosis, the vet will assume that this cat has a urinary tract infection. No urethral obstruction as the cat could squat down and pee normally. Normal coloured urine and no urination problems and other signs indicating kidney failure.

Such a strong odour of urine in the belly. The cat licked off the urine but in the process, his rough tongue licked off all hairs in this belly area. This happened for some weeks. Therefore a prescription of antibiotics will resolve this cat's problems.

Yet the anatomy of the cat's male reproductive system would indicate that the urine stains on the belly could not be from the cat's male organ as it is located nearer to the anal area and points downwards and away from the belly normally. This was a normal cat.

"Something is wrong with your litter box," I said to the owner. Of course, it would be best to visit the apartment. The next best thing would be to listen to what the owner had to say. The owner had never mentioned about the litter habits of this cat as it did not occur to him that the litter box was the cause of the problem.

I mean, the cat goes to the litter box, squats and pees and get out. All normal cats do and this cat has had been using the litter box for so many years. He was around 5 years old now.

Well, the problem was really his litter box. The maid had covered the box well with overhanging newspapers. The cat stepped into the litter box. He squatted and peed onto the newspapers. As he stepped out of the box, his belly was splashed with his pool of urine. This happened frequently such that he could not clean himself but he tried to and continuous licking stopped all hair growth. So he had a patch of hairless belly.

Finally the cat gave up, I presumed. Therefore, his belly had urine stains. He lost his sense of smell.

I anaesthesized the cat. Cleaned him up thoroughly and asked the owner to get the newspapers just fitting inside the litter box. Put some sand below the newspapers. He was to continue washing the belly and giving the antibiotics. He was to come back for a review in two weeks.



I did not expect him to come back as most owners would not do when the cat's problems were resolved. However, he did turn up and that is how I am able to write this report.

"I told my maid not to spread the Straits Times over the edges of the litter box. I also punched holes in the newspapers inside the litter box. In this way, the cat's urine can flow downwards to the lower layers," he said.

The cat's belly was no long bald. The cat smelled good. He was a happy man. His wife must be happier too as the cat now stood by the kitchen door while she cooked curry, wrinkled his nose to tell her that her curry was first class and up to his feline standard.

3. Why should a female cat be spayed?

Judy

We own a 6 month old female ragdoll kitten/ cat and we
were wondering whether it is time to have her spayed.
Our cat has had her early vaccinations performed by Dr
Teo E-Shen, Jason at the Toa Payoh surgery when she
lived with her previous owner.

Can you advise whether neutering is recommended? Being
a ragdoll she is not allowed to roam outside, but we
don't plan on using her for breeding. I assume it is
best for her to be spayed? How much notice do you need
to give you so she can be booked in for the operation?
How much does it cost?

Many thanks for your help.

E-MAIL REPLY FROM DR SING

I am Dr Sing from Toa Payoh Vets. To spay or not to spay a female cat is your personal decision. Most Singapore owners spay their female cats because they cannot stand the loud meowing (caterwauling) which can be a noise nuisance.

For animal welfare activists, all female cats and dogs ought be spayed to prevent unwanted pregnancies and the increasing stray, abandoned and wanted population in animal shelters.

We usually need one day's notice. No food and water to be given to the cat at 8 p.m on the night before spaying. Total cost is estimated to be around S$100.00

Cat -- How to stitch up a very big anal wound?

I am using the Google Docs & Spreadsheets for the first time to document this case. Pictures are at www.toapayohvets.
Be Kind To Pets educational story is to share my veterinary experiences with younger vets in other parts of the world as most veterinary surgical books are too brief on the overall management of the case of a large oval anal wound in a cat.

Jun 26, 2007 3.17 pm

What to do with such a large infected oval wound near the anus? The cat had licked out the fatty tissues under the skin. A big gap of 0.5 cm deep. She had stopped pooping. How to close such a big gap successfully?

1. Ideally, put the cat on antibiotics for a few days. Was the wound. But the wound is large.
2. The cat was fat, at 5.5 kg. Would she be able to survive the injectable general anaesthetic?
3. Anaesthesize the cat using xylazine and ketamine.
4. Clip the hairs, wash the areas. Syringe in 6% hydrogen peroxide.
5. Debride --- cut off dead skin edges and remove dead tissues from inside.
6. Relieve anal sacs of oil. Greyish brown oil seen from left gland. Right gland must have had ruptured resulting in a big hole.
7. Trim edges of wound --- convert to diamond shaped wound.
8. Undermine tissues to get loose skin.
9. Cut lowest end to extend the wound. Z-shaped wounds sutured.
10. Avoid anal sphincter (near the anal ring).
11. Elizabeth collar size 10.
12. Best to ward cat for 10 days but owner wants her home.
13. Warn the owner to confine the cat and if she runs around the home, she may rub stitches off.

14. In 14 days, wound will heal and stitches to be removed.






The owner did not return for stitch removal as she was a nurse in a hospital and I presumed everything was all right with the wound healing.

1. The cat of the night escapes the dog catcher but not his mistress?

"How did your cat survive being exterminated since I saw him with a leg bite wound 2 years ago?" I asked the slimmest young girl with a white head scarf and big-frame spectacles. "Now he has a big lump like a ping-pong ball below his left armpit. It would likely be a cat bite or scratch abscess. There is usually a big muscular tom-cat involved in territory control. Your neutered cat would not be so strong to fight back. Was he permitted to wander the concrete jungles of Singapore?"

"Yes," the girl said. "He will meow so loudly if he was not permitted to go out. So, he goes out in the evening or at 2 a.m."

"For how long?"

"Around 5 hours and he would come home."

The cat had lost some appetite. His rectal temperature was normal. The lump was hard --- an abscess which had not ripened yet.



"I expected your cat not to be involved in cat fights since he was neutered by a vet since I last saw him," I deduced from his left ear tip being cut off a slice. Cats with left ear tips cut off indicated that they are neutered and released into the community. "He would not be as aggressive as the dominant cats after being neutered."

"He was trapped by the Cat Welfare Society and brought to be neutered by the vet last year. We thought he had disappeared for a few days."

"Why not keep the cat at home?" I asked.

"Too noisy," she said. "We keep him at home during the day time."

"A free and roving lifestyle has its risks. I am surprised that this beautiful and gentle cat was not captured by the dog catchers or killed by cat haters. In the past 3 years there was reportedly a team of dog catchers using nets to scoop up the stray cats at food courts and take them away whether they had clipped ears or not." Stray cats with clipped ears were previously not impounded but times have had changed after the outbreak of SARS (severe acute respiratory syndrome) in 2003 and vocal complaints.

"I took pictures of one of the teams netting the cats," the lady said. "Suddenly, a big burly muscular man rushed at me with hands outstretched and shouting at me. I had to run away fast."

"Was he a dog catcher? It cannot be happening in Singapore. Those people you saw could be the outsourced contractors?" I guessed.

"I did not stay to find out," the lady laughed. "I don't want him to know where I live."

I have never witnessed any dog catching team in action. Back to the cat. I asked my assistant to grip the scruff of his neck well. In that way, no tranquiliser was needed as the cat would not suffer pain. This gentlemanly cat did not feel any pain as he was fussed over by the 3 ladies.

I inserted the 20G a needle into the abscess and aspirated out 0.5 ml of greenish yellow pus from the lump.



"The pus smelt of rotten meat," I sniffed at the syringe opening after removing the needle. "This abscess has not ripened yet and more pus will form." .

I continued, "In around 3 days' time, the abscess would ripen and then I could lance it to drain away the pus and debri inside. Sometimes, with antibiotics, it would shrink. We have to wait and see. It is too early to cut the lump."

Would there be another 2.5 years before I see this cat again? After all, he is a stray cat. Anytime he would be impounded. But since he is a cat of the night, he is less likely to be caught. But there are still cat traps around.

The lady who loved cats left with her mother and a sister. An Indian boy of 12 years old cycled to the surgery with a stray kitten with a bluish swollen bluish belly most likely due to being kicked by naughty boys. "My mother asked how much you would charge for treatment of this stray kitten," the boy said.

"I would pay for the treatment," the slim lady said as she put a $50 note down and left the surgery with her mother and sister. "Bill me if this kitten required further payment."

Follow up:
The kitten did not survive the serious injury but the black and white cat recovered at home on antibiotics and after I had aspirated 0.5 ml of the pus from his armpit.
