Aww, I hope Doogie doesn't suffer from claustrophobia! I sympathise with you about the weight. My mum's cat is just over 20 lbs and I have to use two hands when I carry him in to the vet. We had to buy an especially big carrier for him too, and to think that when I brought his litter home from their first vet visit, all four were in a normal sized carrier with space for at least three more!
