He was eating only dry food, also from Royal Canin, for sterelised cats and it is a miracle that he was eating that at all. In general he is very difficult with eating. He does not like meat, fish and likes very much sweet things (cakes, cookies, custard, pudding, cream). In his youth his owners had probably given him sweet porridge so as a kitten his taste has been ruined. When I took him home I remember having difficulties with feeding him. But when he became too hungry he finally decided to eat the dry food I gave him.
If I need new pils for kidneyfailure I will have him tested again for T4.
