Those people are acting coldhearted and mean!

There is one way that you could take the cat without causing any problems. You could say "Hey - I'm taking this cat to the vet. I really think something is wrong with her."

Take her to the vet, and then call her "owners" with the estimate. Then when the hem and haw about the cost, say "Well - maybe I can come up with the $. If I do, can she come and live with me?"

If you "catnap" her they would probably find out later and cause problems, you know?

You know - even if it is her who is having the "peeing problem" it may resolve as soon as you bring her home with you even if it wasn't caused by a urinary tract infection.

Good for you, for doing this! You are her guardian angel.
