My outdoor female spayed cat was missing for about 30 hours, when she showed back up, she was not eating, just very little, not like her, no energy and her right side, both front and hind legs were not working properly. When she would stand, they will slowly slide away from her and she walks like she is guarding them. She just wants to sleep, not like her. She also seems spacey. I can not find any bites or stings on her, nothing swollen. We do live in the country. Please help if anyone has any sugestions. Thank you.
