How many times do I have to say this, its not the birds that concern me. It's the contaminated water. Ill give you that outdoor cats are pretty far down the list of things that need to change ASAP to keep our waters clean, but its also by far the easiest.

Also, thank you for giving them a loving home. That is more important than anything else, it would just be nice if people would keep a handle on them to avoid contamination of our waters.
