Hi, I have two old male rats. None are sick, but I keep on worrying about what I should do after one of them dies. I know people say to get new rats, but the reputable breeder isn't the most responsive and I don't support buying rats from PetSmart, so I adopt. Rats up for adoption isn't frequent either so I'm worried that there will be no options for new cagemates. Is there anyone who has been in the same boat as me? What would you do? Thank you
