My cat once started licking the butter from a slice of buttered bread (which was on the table, just saying). My mom cut out the bit he had licked and - nothing to lose - gave him it. Well… He ate the bread. ._.
Had a black cat who would bite the heads off my Venus flytraps. It was an interesting experience with Salem when it came to trying to raise plants. If he doesn't bite them, he'll knock them down, effectively killing them by spreading dirt and ripping the plant up at the roots.
One time I used rose scented body wash on my legs, and my cat loves the smell of flowers, she started biting and licking my legs. >.> It was amusing, she wasn't hurting me though, she doesn't bite hard on me unless I rub her stomach hard.
My last dog had an obsession with chewing plants in the garden to pieces. She made me so mad when she shredded my ephedra plant, and terrified my mother and I when she tore up our peppers and eggplants.
