Mufasa has also been biting around his penis and anal area and howling while doing this...yesterday. Today, he is walking very little but when he does walk it is very slow and walks like he has a problem with his backside. Does this fall within the symptoms of things you have already described?
It was just as you thought...we got to the vet and they found a very extended bladder and immediately took Mufasa back to surgery. It was a blockage, not from crystals but from some foreign object that "worked it's way in". Mufasa is recovering well at home and we are just waiting for him to urinate on his own now. They told us to bring him back in if he hasn't done this within 2 days.
I appreciate your advise...we may not have acted as fast, which may have been to late, if we had not received the advise from you yesterday. Thank you.

Unfortunately, Mufasa did not make it and passed away Saturday morning. While he did not have another blockage the vet believes that toxins were the problem in the end.
Thank you Dr Z. And thank you for the follow up. Take care.
