How long does cat bladder paralysis take to recover?

Cat bladder paralysis generally recovers in 3 to 7 days. It is mainly caused by urethral blockage or bladder spasm that dulls bladder-muscle sensation, so the cat cannot urinate normally.

Drain the urine by bladder puncture or catheter to prevent rupture, then inject penicillin, streptomycin, and similar drugs; the cat usually recovers within a week.
