Cat, but I don't think it's safe to let one outdoors here and I wouldn't want an indoor only cat. That said, at least one person on the street has one, if I find out who owns him I'll ask about keeping cats around here. I miss having a cat so badly.
Horse, but uncertain living circumstances in the future, and the cost. (I'm on two acres now and my dad wants to buy a tractor to mow the place... a horse could be eating that grass! sigh)
Livestock animals, but I have no interest in them as strictly pets and my dad can't stomach anything dying. Plus space.
Large cichlid tank, but cost.
Saltwater tank, but cost and it's intimidating.
Small boa, but ??? uncertain living conditions, cost, I guess. I might still get one though.
Leachianus geckos, but cost.
Argus or tree monitors, but space and cost and maintenance.
Parrot, but too much responsibility and time.
Ferrets, but wrong living situation.
