I quit giving Toby the kitten food (Piglet liked it more than her own food and ate most of it). The vet told me that at twelve weeks kittens can have adult food. Now I have one bowl of dry food for free feeding all day. Wissel was used to this before, but Piglet got two meals a day and tends to just keep eating now because it's there all the time. She is so heavy I can hardly lift her and I'm thinking about taking her to see the vet for some advice.
The three of them share a big can of wet food every other evening. I put it in three seperate bowls, Wissel eats very civilised little bites and takes her time (a real little lady), Toby and Piglet eat like pigs and attack Wissels bowl when they've finished theirs. Wissel always seems dissapointed when she comes back later and finds her bowl empty ('I was saving that!'), so I give her and extra little treat.
I fed Piglet Iams kitten food when she was little but found it so expensive that I switched to Whiskas, which is what I'm feeding all three of them now.
