The cat is discharged from the hospital when it appears unlikely that obstruction will reoccur, usually 1-2 days later. If he is experiencing kidney failure and toxemia, intravenous fluids and additional hospitalization are needed. Following initial treatment, it may be necessary for you to return your cat in 7-10 days for a recheck of his urine. This is very important because some cats will appear to feel much better, but the urine is still bloody or contains crystals. If medication is stopped based on how the cat appears to feel, treatment may be terminated prematurely and a relapse will probably occur.
Many cats have a recurrence of cystitis.
This is one reason that a virus is suspected as the cause. It is also the reason that a proper diet should be fed in the future. Although we do not believe that any type of commercial cat food causes cystitis, we know that certain things can be done to the diet to minimize a recurrence. Dietary prevention depends upon what type of crystals are present. If struvite crystals are present, they can be dissolved in acidic urine.
