Impossible to choose. I think sugar gliders are adorable, but I'm fond of squirrels, and kangaroos, and tigers, and polar bears, and tapirs, geese, dogs, woolly monkeys, actually... it's all of them. And everything on the list from the OP. And everything else that's alive now or has ever been alive.
I like farm animals-chickens, cows, horses and so on. Not much of a traditional pet person, I choose my animals based on usefulness I guess. I love my animals just like other people love their pets though.
bugs! All kinds of bugs! except for mosquitos. beetles and praying mantisis pwn. I think Pseudocreobroter wahlbergii is a very pretty mantis. It's a flower mantis with wings that are so gentle with, i can't explain it. orchid mantisis are pretty too. I also like the rhino stag beetle.
The animal is ok but it has by far the most interesting name in the animal kingdom.
ITZ MAAAN-BEAR-PIG!
He is half man, half bear and half pig. Okay.
But most other birds too. And I love my cat!
