With that said, I think that a companion pet can often help one make those changes. Since it sounds like money and allergies are a bit of an issue, I would suggest looking at rats. They are incredibly loyal and affectionate, clean, intelligent. They only live about 2-3 years, which sucks, but if you find that pet ownership isn’t for you (and it’s okay if it isn’t), you aren’t beholden to an animal that will live 4-5 times as long.
I disagree, he should kill them…
With kindness!
