Henry had his PU surgery on April 13th, and got his stitches out on Tuesday. Since he got his stitches out I have not seen any pee in the litter box, and just noticed a pee/bloody spot on the floor. He is drinking plenty, he is confined by himself with his drinkwell platinum so I know how much he is drinking. What on earth is going on! I'm taking him to the vet tomorrow, but is this ever going to end?
