You can say that again!
All of my kitties over the years have either been rescue kitties for the humane society or ones from people who no longer want their little sweeties!
Sometimes I wish I was cat-less because they do "tie me down" from taking long vacations and other things but they are my "babies" and who would give away their child?
I have two kitties right now (Cleopatra a Maine Coon and Serenity a DSH). I've had up to 4 kitties at once. They are indoor only cats because it's safer for them (no fleas & ticks, no dogs or other predators, no traffic, traps, no rodents/birds to eat and get a disease, etc).
I even have a plan for their care if I should die before them.
