Spend all of my beer money on their food and shelter?
I used to love pets. Actually, I still do. I just don't enjoy them as much as I used to since my wife has over compensated for her pet-free childhood by filling our house with a retriever, a teacup poodle, four cats and 2 rabbits (there were birds and fish but they've since passed). Now keep in mind, this is in a 1,250 sq.ft. bungalow cape along with four kids. And three of the cats don't get along with the friendliest one and the two rabbits don't get along well enough, unsupervised, so they each have their own cage.
I can see getting to the point where we are pet-free (through natural attrition) for a short period of time before reassembling a more manageable size zoo.
