FABCat is 17 and I took her for a check up yesterday. Our usual vet wasn't there so we saw another one and she had concerns due to FABCat's arthritis and leaking of urine. I opted to wait until our normal vet is back in 2 weeks who has seen FABCat for months and knows her well. We can't treat her arthritis without knowing what her kidneys are doing (she has kidney failure) but she was saying about if she was in pain she would hide away and groom excessively. Are there any other signs?
