I have two 4mo kittens and woke up this morning to what looked like watery cat sick (not regurgitated food) all over the kitchen floor. I offered a tin of a new food alongside their usual food yesterday so assumed it was just a bad reaction, both kittens seemed okay so wasn’t too worried, fed them as normal this morning. Kitten1 didn’t show much interest but this is normal for her so I wasn’t that worried and she did have a few mouthfuls, but a short while later she started miaowing and then was sick again. She hasn’t touched any of her food since but is drinking a little, won’t even touch the freeze dried chicken breast she usually goes crazy for. I have some Untamed natural lick treats which are mainly chicken broth & breast so gave her one of those, she kept it down about an hour but was then very sick again. Should I be trying to get food down her (eg: should I buy some plain chicken breast or something she hopefully wont be able to resist?) or am I better just offering her usual food? At what point do I need to worry? I’ve never had a cat/ kitten be sick from what appears to be an illness before (only from wolfing down food to fast) so not sure at what point I should worry? She does look okay in herself, doesn’t seem overly lethargic right now or in any pain.
I have tried to phone the vet but no answer, there is an emergency line but obviously don’t want to call that for something minor I can be treating at home. Hoping someone with more experience of sick cats can hopefully advise as I don’t want to drag her to vets over nothing, especially as she hates the car, but equally don’t want to ignore something I should be getting checked out. Thanks in advance.
