Croup is a condition that develops quickly in children and is usually caused by a viral infection in the upper airways, which is localised in the throat and surrounding tissues. It's characterised by a barking cough. It's fairly uncommon and affects more boys than girls.
However, depending on the type of catheter you had installed (a urethral or a suprapubic catheter), you may still experience some catheter pain, especially in the case of an indwelling catheter that is expected to stay in your bladder for awhile â usually from a few days all the way up to forever.
Cats that have urinary obstruction require emergency treatment. Sedation or general anesthesia is needed in all but the sickest patients to allow placement of a catheter into the urethra to flush out the plug or force the stone into the bladder. The bladder is thoroughly flushed and drained through the catheter to remove any remaining sediment.
