Hi, I have a neutered tom cat that has just come out of the vets after 5 days on IV. He blocked his bladder last year with struvite crystals. I got him neutered last week and he blocked straight after. He was leaking all over the place after being unblocked. Then a few days later he was very dehydrated and i brought him to vet. his creatinine and urea were very high but have come down alot and last test his creatinine was still a little high. He is squatting frequently producing small puddles of clear urine. Not sure what it going on and he is drinking lots of water.
