Smilla Kitten Poultry

I initially bought a 3kg pack to see how my 6 cats got on. All seemed good and bowls were empty. The poo smell is horrendous. I bought the 2x10kg pack as it's such good value, worth the smell ha ha! Anyway, I started to notice that my big boy was losing a significant amount of weight. He is a dustbin and will eat anything. I realised he wasn't eating at all. Of course you start thinking the worst as he's 12! Back to Royal Canin I'm afraid

They don't really eat it much.
