Our neighbors had two females - awhile back. Cute little things. I would "babysit" when the neighbors were out of town.

One time I had to go out and buy a metal protector for the water bottle. They got bored, with their family away, and kept chewing holes in the plastic bottles.

One year, just before Christmas, the neighbors were heading to Florida. One of the critters had died, and we insisted they bring the other one over here - so she wouldn't get lonely. It was fun having her.

We put her cage on the bookcase, in the dining room. That way she could see what was going on. The cats would get on the table and stare at her, and she would stare back. They all seemed to enjoy the interaction.

She ended up dying a few months later. Their life expectancy is 5-8 years - I think.
