I have two cats both two yeas of age, one male and one female. I noticed a month ago that one of the cats was peeing in my bath tub and on my back porch. I couldn't figure out which one it was until recently. PS both cats are indoors, but this summer they started going outside and they both have all of their shots and are spayed and neutered. I found the male hanging out in my bath tub and realized that he is the one urinating there. On a couple of occasions the urine was red as if blood was present. I've been making sure that he is drinking water. Their diet has not changed as they have always both have been on the same diet of cat food. He still eats normally. I did notice that his bottom lip was swollen, but it appears to be back to normal, but his peeing issue has not changed. Do you know what this may be? Anything will help, I am not sure if he needs to see the vet...
