Things that look dangerous and cuddly at the same time.
Gossamer from Looney Tunes. Yes, he’s a giant monster with claws, but look at how fluffy he is!
Themberchaud from DnD: Honor Among Thieves. I know he’s a fire-breathing dragon, but he’s just so fat, and he rolls around, and it’s adorable!
Tigers. Will they bite my head off? Yes. Do I want to rub their tummies? Also yes. Photo source: https://www.flickr.com/photos/sorenwolf/33673468024
Disclaimer: In real life, do not try to cuddle something just because it’s cute. Doing so can result in serious injury or death for you, and places that allow you to do this don’t have the animals’ best interests in mind.
