Hi, we have had two kittens for two weeks now, they are 11 weeks old tomorrow and seem constantly hungry! They have two pouches of food each per day and some dry food is down most of the day (along with water of course). Every time I so much go into the kitchen they are jumping round my feet and miaowing pitifully as if they haven't eaten for months! How much should they be fed? They have been wormed and due to 'the stolen toast crust with Nutella' incident they have both been checked out by a vet!
