DR SING'S EXPERIENCES

In Feb 2009, I neutered a male cat, 4.5kg
xylazine 20 at 0.1 ml IM
ketamine 100 at 0.4ml IM
OK. Recovers <30 min.

I spayed a female cat, 2.5kg
xylazine 20 at 0.15 ml IM
ketamine 100 at 0.6ml IM
Excellent anaesthesia.
OK. Recovers 30-50 min after the end of spay.

For spaying of female cats above 4 kg
xylazine 20 at 0.2 ml IM
ketamine 100 at 0.8ml IM
Excellent anaesthesia.
OK. Recovers >30 min after the end of spay.

Lower doses may need top up with isoflurane gas (via mask,5%, to effect, usually <1 minutes of gas).
