I have a cat that loves tomatoes. But I think tomatoes are maybe poisonous to cats so I only give him a tiny bite. When we discovered his tomato love, he had gotten into a basket of cherry tomatoes and was happily eating one.
My male cat begs at the dinner table every night even when I let him sniff stuff and he's not interested in the food. His most amusing love is pop rocks candy (yes the stuff that fizzles in your mouth). I originally gave him a fingertip amount as a joke, expecting him to freak out about the fizzling (mean I know, but he's the troublemaker of the two so there exists some underlying dislike) but he loved it. We don't get it very often, but since he investigates all kitchen activity he knows. He's licked small piles out of my palms and we can hear it fizzling in his mouth.
He also likes ice, and comes flying into the room whenever we're using the fridge ice dispenser. He licks the melting cube off the tile like a popsicle.
Unfortunately he also will eat anything stringy, he chews and swallows all the tails off his toy mice, even the felt ones, chews up and swallows rubberbands, ribbon, snagged carpet fiber etc. I'm seriously worried he's going to end up in the ER for intestinal entanglement b/c of swallowing long strings one day. We try to moniter what we leave out, but he doesn't follow the no counter, no shelf, no table, no desk rule that we enforce with squirt bottles and reprimands.
Of the heart-aching, hard-working, hope-having, horse-loving and horse-less variety. We are a sad species indeed.
