Hiya,

Thank you for your reply.

I'm using Oko Plus, Cats Best litter. I didnt think about them not liking the litter (We must have tried about 10 with our other cat) but thought maybe as they had both already done stuff in there that it couldnt be that?

I do try to feed them at the same times yes, but its not rigid. Also, Ive caught them both tucking into the adult food which I put down too. Thought when I feed the cats, I tend to put Kipper & Chips (The 2 adults) in one room to eat and the kittens in another.

I cant watch them constantly at the moment, the front room they are in is the not the room I spend my time in, but it will be from next week (Long long story!) So I guess when I am in there more next week I will be able to watch more closely. But it is hard with 2 young children and a huge tum of my own!

Not heard of the non-bio thing, I only have bio liquid at the mo but I will certainly give that a try.
