my cat is a porker!!!!
..... but in all fairness she gets fat in winter so she can stay warm and she gets slimmer in summer so she can stay cooler (shes mostly an outdoor cat since i developed allergies ....lol..... and she used teh fireplace as a litterbox, so she got kicked out)... but still, i think she will end up weighing more than toby, even when he is full grown....
