I'm sure he's doing this on purpose! After searching far and wide for a better cat food since reading the food thread I found something with a higher meat content. So marching home feeling all pleased with myself I eagerly awaited the next feed, carefully mixing his old brand with new so to get him used to it. He wont touch it. I tried a different flavour and all he did was pick out the bits of old food he likes.I've tried different ratios ol old to new but no. He normall enjoys his food but is not for having it. I'm a bit worried becasue he's going for blood tests tomorrow for his allergy and as a precaution incase he gets sedated I've not to feed him after 6 tonight. So he's going to be one very hungry kitty if he doesn't eat something.
