I have something I've never experienced before with one of my kittens and wondered if anyone else has had similar. My persian is now 7 months old. She is a funny little character and very intelligent. However every so often she goes through a period of what I call "nil by mouth", for between 24 and 36 hours she won't eat anything at all. During these periods she shows absolutely no interest in food. Often she won't even sniff at the plate! At all other times she eats well and some days I actually struggle to keep her filled up and she squeaks for more! She has been like this ever since she was weaned and I'd say it happens once every 3 or so weeks. She doesn't vomit and I can't say I've noticed a change in her toileting at these times. She remains normal in all other respects apart from the not eating. She only eats wet food (by her own choice) and gets a variety of grain-free options plus some raw. Neither her sister or mother display this strange eating habit. So what could be going on here? I'm baffled!
