Randi ~

We've been through some of this...

Bleeding from WHERE??
Blood mixed in with the urine??? Or from somewhere else?

Blood in the urine - may look nasty and red - isn't a red-flag emergency as long as it's pretty wattery and not THICK as if it were pure blood.

Does he Still have the Catheter Installed; or did they take it out after he was flushed??

IF Fister hasn't been drinkin by himself for 2 days - He NEEDS to be force-fed some water.

Best tool to force water is a syringe - with the sharp needle part REMOVED.
No syringe? A kid's squirt gun or something similar will work...

Hold him with your hand over his head - thumb on one side of his jaw and fingers on the other side of his jaw -
gently apply pressure to the hinge of his jaw - he'll open up...

Squirt about a TEAspoon of water WAY back on his tongue - he'll swallow most of it and shake the excess out (all over you!)

He should be OK as long as he's not Completely Blocked and cannot eliminate any urine.

How many hours will it be before you can get him in to see the Vet?
