Mama is conflicted........

When Mama went food shopping, she bought a bag of "cheap" cat food for the stray kitty. When she was feeding him/her today, Mama checked the front paws & Stray Kitty is declawed. We knew he/she belonged to someone because of how friendly he/she is, but we don't know if he/she is lost or has been abandoned. Mama just knows that declawed kitties should be inside kitties. That's where the conflict comes in, Mama hates to leave the kitty outside, but she doesn't want to stress us out by letting him/ her in. That & we have no green papers to take the kitty to the v-e-t to be checked out. Mama is just sick to her stomach worrying about the kitty. She knows if we were lost, she would want someone to take us in & take care of us. Does anybuddy out there have any suggestions??
