I guess it depends on how "small pet" is defined. I have a few pets that may be considered small by some people and other may not consider them to be small.
I have 9 birds- 2 are cockatoos though and probably wouldn't be considered small. I also have 5 snakes- 2 wouldn't necessarily be considered small. I have 3 chinchillas, a prairie dog, and 4 tortoises (3 are actually mine, 1 is a long term house guest). I also have an iguana, but he isn't too small.
