My lovely 17 year old male cat was recently diagnosed as hyperthyroid. He's a bit of a pampered beast, and normally has a wide range of foods. However, we decided to try him on an iodine-free diet initially (Hills y/d), because he's a house cat who doesn't really want to venture outside and because we are occasionally away for work and it will be easy for the neighbours to 'treat' him if the medication is a diet. However, there is an alternative treatment available in the shape of a gel that gets rubbed onto the cat's ears (also, pills as a third alternative).
We started the diet 2 days ago. He was VERY keen on the first bowl of crunchies and first can of wet food and scoffed the lot. However, yesterday he decided he'd gone off them and is refusing to eat anything.
There is an element of protest here because he's very used to getting his own way, particularly with food. I feel terrible that he's not eating with his usual gusto! How long do I continue this battle of wills? When should I become concerned that he's not feeding properly?
I realise I sound like the worst kind of pfb parent here!
