I’ve found it varies - some of my cats have got back in the carrier, some not. Phoebe doesn’t want to get back in - I’d much rather she did!My cat always goes back in her carrier, on the floor, when they are done with her. She wants to. Maybe the vet just figured the cat would want away from him /her as soon as they were done? Am I the only one who doesn’t find this the least bit strange or bothersome?
