We had a cat that seemed to be having the same problems yours is. ( This was about 15 years ago though ) After a week of seeming to pee all the time and in many places he woke me up early in the morning yowling in the kids bedroom. Took him to the vet and he was blocked up with crystals. The only answer was for the vet to break up the crystals ( he didn't say how it was done and I was afraid to ask.) Told us it would be about 250.00. We didn't have it. Told the vet all I had was 100.00 dollars. After many tears from me my husband told the vet to take care of him and we would find the money somehow. After a week at the vets he was good as new and lived another 12 years. The nicest thing was when we picked him up the vet looked me in the eye and said he guessed he made a mistake when quoting me the $250.00 and the bill was only $100.00. I send lots of blessings and thanks to that DR.
