Rodents? Are they gerbils, hamsters, rats?
When I was a single man my live-in companions were gerbils. If I didn’t have a dog I definitely would like to raise some rats, based upon what I have read about their intelligence.
Gerbils. We got the first two about ten years ago, and every three years or so, we have to replace them. I don’t think they have as much potential intelligence as rats, but they do have personalities, of a sort, and they’re easy-care.
