My brother has had a tarantula and a hedgehog for pets, oh, and a pot belly pig, he also likes to plant/grow exotic plants like fruits and vegetables and hops and nicotine, he's a pretty good cook too. He says he is more in touch with his feminine side then all his sisters put together, but I have no pets and have no desire to obtain one.
Parrot a really really smart one I'd train it to say bad stuff so I don't get in trouble and train it to poop on people I want and tear my homework and say that to the teacher if he doesn't believe me the parrot will say naughty stuff and stick middle toe up at him haha
A baby marmoset monkey. You can buy them already. Lol. Plus, the people who own them treat them just like little babies.( dressing them in clothes and diapers, bottle feeding them.) they are the cutest things and don't get much bigger than your hand(the babies are as big as your finger) :)
