I think they are always animals. Afterall, they are almost always described as moving in someway... I can't really see a chair charging towards a dementor.
Holy crap Beauty and the Beast all over again.

I think Voldemort has a Patronus like the other wizards and it is a giant snake. Voldemort has a strong connection with snakes. I think a giant snake is suitable for his Patronus.
If you observe closely when the students secretly practice conjuring their patronae in the Room of Requirement, Ginny Weasley conjures a horse, not a swan.
In the books and in the movies it's stated that all patronus manifestations are totem animals, guardians. I find it interesting that Harry conjures a Stag while Snape conjures a Doe. _________________ Walking on water is hard but running is easy. The greatest wand is in yourself, not your hand.
