Took my 6 month old kitten to the vets today. She loves the car and regularly comes out for a drive, no issues in the past. Today she was sick everywhere. She had her nails cut and got weighed. Been weighed previously and she didn't seem bothered by nail cut. She came home and instead of going out to play she took herself off to bed. Been there literally all day, only woke up to eat and drink then straight back to bed! 😔 Could she just be sulking or should I be worried?? She seems sleepy and sad.
