Wow, Sen! Perhaps part is down to my own tastes which very much enjoy a curry and spicy things but couldn't take a lot of heat (and don't get the vindaloo merchants...) but I've never imagined a cat liking something hot and wouldn't try it on a cat.

Off hand,maybe the closest I get to is Mewan who did like a nibble of brown bread and Marmite. Even that was funny, the way she'd wash her face after but she liked it.
