I love these threads!
We have a cat who disappeared the second week of October. We assume she got out through a broken third floor window.
Last weekend we "found" her in a closed closet on the third floor. She was MIA for 5 weeks, and when she was "found" her coat was still glossy, she wasn't especially hungry, wasn't dehydrated and her eyes were bright.
The best we can tell, there is some cat egress and ingress from the roof to the closet (we've looked and can't find it) and she lived on the roof. But how does a declawed cat catch birds?
