Cats love to eat. And eat. Darn near anything.
Most particularly, Snaps - who is a rescued stray - loves to eat: as though he doesn't know where his next meal is coming from (he does know, of course, because he always comes running at the sound of the cupboard door being opened). He has pretty much doubled his weight since we took him in, last fall. My guess is that he weighs at least 15 lbs., now. He is certainly not the svelte orange tom-in-need-of-fixing we allowed into the the laundry room to escape the rain.
He seems to have levelled off at this weight, finally comfortable that he has enough spare fat on his frame to see him through whatever befalls; but he is still hungrier by far than the rest of our furry horde. Rather than just let him have an extra bowlof kibble, however, we have started to give the extra snack in the "puzzle box".
