Haha! We have a feline Hoover at our house; that's what we call our cat vacuum cleaner. She'll eat almost anything that drops on the ground... or that we even accidentally leave on the counter! She knows she is NOT supposed to go up there, but that never stops her, unfortunately.
Since adopting her (she's the white cat in my avatar) we've had to learn that we can't even leave a loaf of bread out, even if it's still in the store bag. She will chew through it and we'll find bite marks and nibbles taken out of the loaf! Although I find it amusing, I don't think my mother enjoys throwing away the slices of bread that have cat tooth marks in them. But she's the one who keeps leaving the bread out, even though I keep reminding her!
Clawdia doesn't touch fruit or vegetables of any type, however, which goes to show that even though dogs are omnivorous, cats aren't.
So it's not just my cat who eats bread XD There's not much he won't eat though, to be honest... I've seen him eat potatoes and even vegetables, although he won't touch fruit :3 It's funny how some cats eat just about anything but other cats are really picky about food.
