My cat (who is a bit of a pig, was on a diet and is now at target!) has become increasingly whiney over the past few weeks and is constantly asking to be fed - sometimes just a short while after his feed. I've wormed him - but is there anything else this could be apart from him just being a gutsy pain in the arse? He's driving us nuts - the minute we wake up he's crying to be fed, to the point where he wakes up the house. He has been on a senior food for a few weeks - not sure if this is just not providing enough bulk so have added few IAMS biscuits.
