Aw, bless your heart! That's nice of you to give her a little extra time! Is she pretty feral? How awesome that Carmy has been able to pet the little boy. Maybe there's hope for an adoption later. Will the shelter take him if she can tame him up a bit, even if he's a little older?
Also nice that the shelter has the TNR program--I'm not sure that ours does, but they may these days. I haven't asked them about it recently. That won't cover immunizations, though, will it?
We saw our stray last night, too--whew! I was a little worried about him. He appeared to be mousing in the front yard under the bird feeders after dark. More power to him! He can have all the rodents he can catch!
