My 12 year old Bengal has been through the mill recently. He had an abscess that needed draining under GA. Took a few days to get over the anaesthetic. During his check up, I mentioned he was still lethargic and sleeping a lot. Blood tests were all normal and scan revealed nothing. Turns out he also had a severely infected tooth with a pus filled cavity which had to be removed under second GA. On day of collection, his pupils were different sizes so the vet initially though there was something neurological going on but I spotted a mark on his eyeball which turned out to be a geographical ulcer caused by herpes virus flare up brought on by all the stress! Now sorted with antivirals and eye drops.
In order to control his pain following the extraction, he’s been on a fentanyl patch. He’s eating well and using the litter tray appropriately but seems spaced out and occasionally staggering when he walks - if that makes sense? The vet seems to think that it would be very unusual for fentanyl to have this effect, but when I’ve googled it, it seems like it’s actually a very powerful opiate which would fit with the behaviour and the advice was to keep him in whilst on it.
Just looking for reassurance and has anyone else had a similar experience and did their cat quickly return to normal following the patch’s removal?
Many thanks.
