Thanks ladies I actually did a little more digging and found this:

which sounds like what Stevie has. It's likely that Stevie has an obstruction which is blocking his urethra and mom was a little confused perhaps. I'm going to call her today and see how he's doing and if the vet was able to get a catheter in and if he may need to have that surgery. I was just so shocked when she told me yesterday that she didn't think he would make it.

Hopefully the vet was able to figure something out!
