We tried giving the cats a corn cob, corn still on it, to play with this weekend. Neither cat was interested. Even tried putting it on their ‘food’ plate. Nope. They just looked at me like I was teasing them. 
Was worth the shot though. 
Neither of them likes catnip, either, and one of those little ‘cat greens’ dishes that I grew for them immediately became a tug-of-war object, as they gripped the greens with their teeth, not to eat it, but to drag it around the house. >< My cats are dorks.
My huge tuxedo cat, Dominic, loves watermelon, honeydew, blueberries, peaches, and plums. He will also spend ten minutes rasping all the pulp from an apple core.
On the other hand, he turns up his nose at meat, fish, and other carnivore yummies including people tuna!
We have decided that he is a reincarnated Buddhist.
Well, our finicky feline, Mr. Tibbs, certainly has highfalutin gastronomical tastes. We, his human caregivers, must subside on such pedestrian dinner fare as Kristal belly bomb burgers in order to finance Tibby’s unquenchable appetite for premium caviar: Beluga earns us an approving head rub; Sevruga earns us his backside to the face.
The cats will literally come and cry in the kitchen if they smell cantaloupe being cut. They aren’t interested in the cantaloupe flesh, though, only the juice.
The dog has trained me to put down the plate for her to clean after I have eggs-over-easy. She likes the yolk remainders.
This isn’t strange, but I have learned the hard way that the price of a tuna fish sandwich in this house is eternal vigilance. I once had the dog approaching from the front, and a cat coming over each shoulder.
When I had dogs, they loved ice cubes. Would sit in front of the refrigerator and beg for them. Had to watch the mixed drinks, too. Under cover of darkness, post-party, they’d scout for unattended highballs (usually consisting of scotch, bourbon or whiskey) left out after one of my parents’ parties and help themselves.
One of them also adored chocolate and was a past-mistress at sneaking pieces of it without getting caught. One day I was sitting on the couch reading. There was an Easter basket full of individually-wrapped chocolate pieces sitting on the coffee table directly in front of me.
Bold as brass, Schatze loped by, turned her head just so, and snagged a piece from the basket with her tongue without even breaking stride. It was so fast and so smooth I wasn’t for sure I saw what I thought I saw until I witnessed it for the second time in a half hour.
Of course, we all know chocolate is bad for dogs. We didn’t think about it being within her reach, since the candy was individually wrapped in foil/plastic. We thought she wouldn’t be able to smell it. Obviously the dog was a lot smarter than we were. She apparently had no trouble digesting it (foil and plastic as well) either; however, that was the end of the Easter basket left out on the coffee table.
My cats are all boringly normal. None of them over the years has displayed anything strange in their food tastes.
My wife loves avocados, I detest them and I was so proud of our dog when last week she stuck her nose up at a piece that had fallen on the floor.
Our dog likes grapes. Not sure how unusual that is.
Our Bernese Mountain Dog loves:
Bananas, cabbage stalks, butternut squash, apples, pears, spinach, carrots, celery, cucumber, tomatoes and assorted road kill.
In addition to this, as far as she is concerned there are two types of poo - the type you eat and the type you roll in.
It’s completely disgusting but we love her anyway.
My dog, who looks like a ridgeless ridgeback, will eat almost anything. Cigarettes butts off the street if I’m not fast enough is probably the strangest. I think he had a little nicotine problem for a while there until I caught on to why he was searching the gutters.
Paper towels, whole packs of chewing gum, toothpaste - really anything “minty”. All veggies and fruits except for grapes, which seem to confuse him.
The one thing he absolutely will not even taste is diet dog food. We tried it once and he refused to eat for 3 days until I gave in and bought his normal brand. How awful must that stuff be?
When I was kid, we had rescue pug that went ape-shit crazy whenever someone ate a tangerine. He could be sound asleep, in another room, and someone started to peel a tangerine, he would wake up pester the person peeling the tangerine unmercifully. He was pretty well behaved otherwise.
