Believe it or not, some people get tired of their old cats, and trade them into the local pound for a new young kitten. These cats don't know why their lives have changed so much, and just want things back to the way they were. These older folks still have years of vibrant life ahead of them, and just need someone to make their lives full again. Don't let these lovely cats be forgotten forever, please contact us right away.
That is what is wrong with how people these days view animals, they are simple commodities. Products to be bought and sold. Don't like your current cat? Get a new one.
I have two dogs and a cat. One came from a breeder, one came from a farm and the other came from the shelter. I have two mutts and one purebred. I would never think of "exchanging" one, let alone exchanging one for another at a pound!
