Update: Obi is home again. He finally went pee pee at the V-E-T, and yes he has blood and sediment, but no crystals in his urine. He was given sub-q fluids and an antibiotic and a steroid shot to help him along, and now he is on Buspar for anxiety. (He gets over-stressed around here what with Dorf and G.T. bugging him, and him being a highly sensitive orange cat he is a bit emotional at times.) So, he will be on Buspar during his FLUTD flare-ups, which can be exaggerated by a Herpes flare-up which he is currently having one of those right now as well. So there you go.
Previous post: Our beloved Obi is at the V-E-T. You see, yesterday morning he got up on the bed and pee-pee'd right there on the bed. Well, Paw was all like, "You need to take him to the V-E-T!" And Maw has figured something was bugging Obi anyway since he hasn't been hanging out much with Maw and sitting on her as frequently as normal. So, off Obi went to the V-E-T yesterday afternoon. Well, since it is a huge ride of 5 whole minutes, he went pee pee in the cat carrier, but there was a towel in the carrier. The V-E-T suggested that the next time we have a cat with urinary problems that we leave the towel and just bring the poodin in the crate. Now why didn't we think of that???? So Obi stayed overnight at the V-E-T and STILL HASN'T GONE AGAIN. Duh. Anyway, it is probably another bladder infection. Remember, he is the one that had the perineal urethrostomy done; i.e. leaving him a different "opening" than your typical male cat for previous blockage problems.
So, we are awaiting word on what medicines we need to give the kid once he comes back home.
