I hope somebody can help me!! My two 6 month old kittens were castrated last Friday. Everything is fine, they have bounced back really well, except they seem to be starving hungry all the time! They only missed one meal on the Friday, their breakfast, post-op they had chicken and rice as vet recommended. Since then I have given them their normal diet of Felix sachets morning and evening, with dried stuff down all the time. Plus lots of treats of Dreamies and cheese to relieve my guilt! They wont stop bugging me for food, maybe cause I'm off work this week, but it's non-stop. Is this normal? Should I feed them more?
