I don't like insects but some people are fascinated by them. Ant farms are kind of fun though.
I don't like any animal in a house and will never allow another one in my house. Dogs and cats, the most popular pets, are inherently dirty and, while cute, they belong outside of the people house.
I only like dogs if it's my own dog, other people's dogs kind of annoy me but that's because a lot of people let them misbehave and jump all over strangers. It's especially annoying when they walk their dog without a leash and they come by my house while I have my dog on a leash and going potty in my own yard, then their dog comes running over to greet us and makes my dog go ballistic and I have to wrangle her in and take her into the house so the idiot's dog doesn't get mauled..
