HEALTH UPDATE
The woman who has the kittens now reports the following:
"They've been to the vet once, had a first round of shots (FIV, FELV, Rabies, Distemper) and dewormers. I can provide a copy of that paperwork. They haven't been tested for FIV and FELV (the vet told us too early could give false positive results) but momma cat has been tested and is negative for both. Physical exam was unremarkable and they seem to be in excellent health.
"They haven't been fixed yet, but if they're here much longer, they'll need to be."
So . . . . . ?
