Loved by all our cats, especially the toothless one!
Our three cats eat a balance of wet and dry food, and this has become their favourite of the dry foods. In particular, it's the only dry food which suits our elderly cat who has no teeth! She can't chew them so they just go down the hatch in one gulp, but she loves them. Because of the shape of the biscuits (about 12mm in diameter and circular with a hole in the middle) she seems to be able to pick them up more easily, whereas a smaller kibble just falls out of her mouth. She also has kidney disease and a poor appetite (and won't eat special kidney diet foods) so these Optimanova biscuits are what we give her to keep her nourished, since she will always accept them even when she's refusing other foods. We have tried other flavours in the range, but the chicken one was definitely the favourite for all our cats. Not all of the flavours have the same kibble size/shape: some are slightly smaller without the hole in the middle. Not that that's a problem for most cats, but our toothless cat definitely finds these bigger ones easier to grip!
