Maybe I missed this, but Does Fister Still HAVE the catheter IN him, or did the Vet 'flush' him and then Remove the catheter??

If the catheter is still installed, then Fister won't have any control over when he 'pees' - the catheter drains any urine that appears in his bladder... He'll dribble almost constantly.

If they removed the catheter after the blockage was removed and they flushed him...
Without the catheter he COULD block up again and not be able to eliminate his urine when he feels the need (bladder full). Without the catheter - he needs to be monitored closely to be certain that he's both Drinking AND Eliminating urine. If he plugs up without the catheter to drain his bladder - when the bladder becomes full, the kidneys will stop producing urine (no where for it to go) and the toxins will build up in the kidneys = Red Flag urgent medical emergency.

Boots had a catheter twice (and came home for three or four days with it IN) - No problem producing & eliminating urine while it was IN - but he started plugging up a few days after it was removed. Luckily I caught him straining to urinate each time he plugged - and rushed him back to the Vet to be re-cathetered. Twice was enough - the Vet said he was probably going to plug up again - and we scheduled the operation immediately.

Summary: If he doesn't Have the catheter IN now - YOU guys need to be monitoring him very closely...
He could plug up while you're waiting for his hospital appointment.
