My cats are very strange.. they will go NUTS for certains human foods. I dont let them eat much of it when I do give them some (because I dont really know if its good for them or not) But they go crazy for the strangest things.
Examples:
Olives: manzanilla, ripe, kalamata... they seem to smell them a mile awhile and come running... they will eat them if I give them some. They are even are obsessed with olive brine. If I've drained a can in the sink they will go to the sink and try to lick it out. So weird!
Canned Corn: Not corn on the cob or frozen corn... just the canned stuff. Whole kernal or cream style - they like them both! Just like with the olives, they can smell an open can of corn from far away and come to bug me for some.
Cooked onions: Only my black kitty, Panther, likes these. It's so strange though.. if I am eating anything with cooked onions in it he is all around me wanting some.
Butter: This one isn't too strange and I think most cats love butter. I have to remember to ALWAYS put the butter plate back in my fridge. If I leave it out, even for a second (and even with the glass lid on!) the cats will figure out a way to lift the lid off and help themselves.
Condensation on a glass: If I have a glass with ice in it and a cold drink my orange kitty, Ginger, always wants to lick the condensation off the side of the glass. Weirdo!
Some more normal things that they enjoy are fish (haddock, salmon, tuna - any kinds!), shrimps, and kippers. Oh and cheese too! They go crazy for cheese.
