Quite Urgent - Can’t keep collar on newly spayed cat and can’t get her into a body suit

[Legwork]

Im scared stiff - she got her collar off within 2 minutes of getting out of the carrier. It’s extra small and there isn’t room to get a little finger in but she can tip it off in a moment, over and over again. . Dashes to pets at home and bought one of the suit things and have spent half an hour with three of us trying to get her into that, which is not a good idea with stitches and she just wriggles out of it every time before we can do up the final popper. Dashed back to pets at home, bought normal cat collar and threaded that through the plastic one - did it up with I thought was bordering on cruelly tight but she’s got so much purchase on the plastic cone that she can drag even that over her head. I’m so scared all this exertion and then three of us trying to wrestle her into a suit while she has internal and external stitches could be disastrous. She was so exhausted in the end that she fell asleep the second we stopped trying either the cone or the suit and put her on her normal bed. She’s now sleeping peacefully so safe right now, but I’m at a loss on what to do now. In the multiple occasions we gave her a significant breather she showed zero interest in the wound - licked the cannula wound a couple of times before we could stop her, but ignored the stitches. What the hell do I do? 😞

I have to say my kitten did force her cone off, and ended up worrying her wound, so that it got infected. Which resulted in more trips to the vet and some lovely antibiotics! We ended up with a very firmly secured cloth collar, which she tolerated a lot better than the plastic one. There were also several body suits, all of which were either too small or too big, but made for some hilarious photos.

If she's accepting the cone now, leave it on.
They're often really manic post op as they get an injection to bring them round which can make them really hyper.
Then they sleep off the anaesthetic.
The vets give a strong painkiller for the first 24 hours - you may or may not have been given something else for any discomfort after that? I don't think ours needed it.
After a couple of days as the wound heals it can feel a bit itchy - at this point being able to discourage them from over grooming is helpful.
Most cats recover really quickly from spaying.

You can also get a sort of inflatable collar, like a donut that's easier to wear than a cone, but stops them turning around enough to lick.
