Better question would be anyone with an animal without an attitude of some sort.
3 cats - Scardy Deck'ster afraid of her own shadow and very insecure when Simon is not around, Cuddly Simon who will pee on anything left on the floor towels, clothing, backpacks etc

good thing he is cuddly or he would be gone and Grumpy Baxter the old man, sits in the kitchen and will swipe at ankles and hiss until he gets fed, sits in DH's chair and hisses at him when DH tells him to move, will swat at DH if DH tries to move him, our housekeeper was afraid of him for years. She said Baxter would sit on the dryer and hiss when she was moping the laundry room.

Beasts, the lot of them
2 guinea pigs - mine can be nasty....she likes to be petted, held etc, in a certain way and if we do it wrong she nips, complains and looks really annoyed. They love lettuce and will hide the other veggies (peppers/cucumbers) in their hidies and under their litter in an attempt to convince us they are starving and get more lettuce. My piggy is also ticklish and hates to have her tummy touched.
My DD's piggy is super sweet even gives "kisses" she licks DD's hands and cheek.
