my cat had his teeth cleaned at the vet 5 days ago. he was fine until 3 days ago. he is eating very little and drinking little as well. he is sleeping alot and wants to be left alone. he is generally a very healthy active young male who stays indoors. could this be a virus he picked up at the vet?
This could be anything but I recommend that you call the vet and have him checked out asap. Good luck, vetcare
