There is a cat is in my local area. I know there is a lady who feeds it but the cat is mostly out and about, even over night, so I don't think she has an official owner. I have noticed she is getting in increasingly bad condition, her fur has large patches missing, she has some redness on her fur too, she has a large swollen stomach. Should I take the cat to the vet? I don't know where the lady lives who feeds her. I think she is mostly a street cat who just goes to the lady to be fed
