I'm so glad you took him home and it didn't result in bodily harm (for you, lol).
When my sil rescued a cat from the park, she was afraid her husband (Tony) would be mad. So she shut the cat in the guest bathroom right before Tony came home, thinking he wouldn't notice. The door to their guest bathroom is usually kept open. "Why is the bathroom door shut?" Tony asked, of all things. "Oh, I don't know," Sil replied innocently, not believing her bad luck. "I'll open it," Tony said. About that time, the cat started sticking his long front legs out from under the bathroom door and waving them around. "Have you got a cat
in there?" Tony asked. "No," Sil said...
I don't think Sil had much of a plan, it being another one of those spur of the moment rescues where you know you're going to have to face your husband sooner or later. But the good news is, she got to keep the cat (Tony Tiger), who now rules the house.
Blessing to you for your rescue and best of luck in finding a good home for him.
