I AM PRESENTLY FEEDING A STRAY CAT. HAVE BEEN FOR MONTHS. SHE APPEARS TO BE PREGNANT, AND IS INFESTED WITH FLEAS AND EAR MITES. IF I CATCH HER CAN I BRING HER IN FOR CARE AND EVENTUAL ADOPTION?

Since it's kitten season she may be turned away as MEHS and others are to capacity. Mama cats and babies also have a chance of being euthanized due to their requirement for care/need. You can volunteer to keep the cat and kittens as a TEMPORARY FOSTER and shelters should pay for their health care/vaccines/spays,etc. If you cannot foster, then reach out so several other foster organizations near you. If you're near Edwardsville then check out Partners for Pets, Gateway Pet Guardians, or Animal House Cat rescue.

I would try and call them Monday but I doubt there open try Tues and call them they should take her but I don't know
