I would love to have small dog or cat. I can have a dog not exceeding 25 lbs, here where I live. I instead bought a singular gold fish that I call Ralph. I could get too emotionally involved with a dog or cat but not a gold fish. Ralph will live as a loner like me and if he goes belly up, no big deal, just flush him down the toilet and get another fish, maybe two just for the halibut.
