My cat is sick and puking. Can they catch human or outdoor cat flu?
It is not likely your cat(s) "caught" a stomach bug from you. It is more likely the outdoor cat was exposed to an illness which he brought back.
Ideally, you should have them examined by your veterinarian to diagnose illness or injury. Supportive care, such as IV or subcutaneous fluids, anti emetics and antibiotics, may be indicated.
If this isn't possible, try a 24 hour fast followed by a bland diet fed in small, frequent amounts until symptoms resolve. Transition slowly to the regular diet afterwards. If It doesn't help, you'll definitely need to see your veterinarian.
