Do you mind if i ask why you want to wean it off whiskers?

We used whiskers kitten for our boy (and all other kittens we have fostered) and he has always had a thick glossy coat, good stools, healthy gums etc.

We provide kitten biscuits in the form of Iams kitten which he has access to all day with fresh drinking water.

Now he is a year old we have weaned him on to Purely (Iams adult wet food didnt agree with him) and currently he is still eating the Iams kitten biscuit simply because he hasnt eating it all yet and im not wasting a kilo of dried food, lol. Once the biscuits have been used im still debating Iams adult biscuits or more likely a dried food made for hairball prone cats!

So i guess my question is why fix it if it aint broken? (i.e changing him from whiskers to another kitten food)
