Hello all, haven't posted here before but I am fast running out of options and need someone to put this into perspective for me...
Poorly kitty appears to be suffering with possible lower urinary tract disease, or urethral stricture or spasms, no one seems to really give a definitive answer!
He's been treated when he's been unable to urinate, 6 times in 4 and a half months. Each has included everything from metacam, diazepam, antibiotics, vetergesic... And one surgery after completely blocking to insert a catheter.
Today he was back at the vets again, put on a concoction of drugs and told if he hasn't urinated by morning he will need another surgery
the poor boy is so off his face on these meds he can barely walk properly, and certainly not straight, he's basically stumbled and fallen onto my lap and is now asleep face down! 
my question is where do we draw the line? I know it seems extreme? But this is hardly fair on him, at least once a month we have to cart him to the vet, stressing him out whilst they jab him with needles, I hate watching him hiss and cry in pain. And then there's the financial implications, I'm fast running out of money, putting him to sleep is the last thing I want but I just don't know what else to do
