I am worried about my 5 month old cat. She has become lethargic, moans when picked up and she drools a lot. I don't know if its normal for a cat to drool, I know some dogs do but do cats? She has also started hiding for hours at a time. We searched our small house for 2 hours and still couldn't find her, she was eventually found in my sons room.
I am getting her spayed in 3 weeks time should I leave it and mention it to the vet then or contact the vet sooner?
this is highly unusual behaviour for a kitten, so I would advise your to take them to the vets ASAP. if she is moaning when you pick her up, it sounds as though she is in pain.
