My old cat drank toliet water, and my dog that died two years ago used to steal my cat's cat food can...and then brought him back the empy can. It was cute. :)
Our newest dog pooped bright green balloons the first day we got him.
We call him goat dog, because he'll eat just about anything. Rope toys, stuffing, grass, leaves, mulch, twigs, lunchmeat, icecream, cheese, carrots, tomato, ice.
And our other dog eats flies if you don't get them before she does. She used to eat junebugs, before she was civilized.
