Happy Cat Family

Hi, meowmy here!
Thank you so much for all the purrs and good wishes, Bugsy and I really appreciate it.... and I think they are working!
Had a visit with my vet yesterday - didn't take Bugsy with me, but wanted to sit down with him, take the X-ray for him to take a look at, and discuss Bugsy's situation in length.
First let's talk about the X-Ray: The ER vet had thought his kidney looked a little weird on the first x-ray, but on the second one, it came completely normal... She thought it might be a matter of positioning during the procedure, but she wanted me to take it to him to discuss. He said it looked normal, really could not see anything out of the ordinary, and that it didn't look like I should be concerned.
On to the UTI: He thinks that what he has is cystitis/inflammation brought on by stress, which does make a LOT of sense.
I left to Florida Monday, and my friend Donna, stayed here in my house through Thursday - she was a new person, who he had never seen... She got here right before I left for a whole week. When I left in the morning he was acting absolutely strange, completely freaked out... I had never seen him so stressed like that in my life... He kept running to me and away from me completely confused, as though he didn't know who I was... Maybe because I slept on the couch and she on my bed with him... I don't know...
That week he spent alone with Donna and Kelly, the pet sitter. They are both huuuuge pet lovers.... but were not me. They said he was completely happy throughout the week though... I got home Friday night, and disaster stroke Saturday night. Maybe it was just too much stress with me coming and going and new people in the house...
The feliway was late to get in the mail, so only got here on Wednesday or Thursday...
Anyway... The vet also said what makes he thinks this is cystitis/inflammation, is the fact that he is urinating blood. The antibiotic, he says, is not to cure an infection at this point, but to prevent an opportunistic infection that might occur due to the broken capillaries on his bladder/urinary tract, so Clavamox will do just fine. The plan is, if he continues to pass blood by Wednesday, he will go in for a steroid shot to bring the inflammation down.
The vet's main concern is his future bladder health -he said he is not too concerned about this episode, but since he does have immune mediator disorders, such as his stomatitis and IBD, he might be prone to cystitis as well - he NEEDS to be in a bladder health diet.
I discussed with him the fact of Bugsy being allergic to chicken, and he said this is secondary now - his bladder is more important, as this can kill him, and can kill him fats if he gets blocked.
So.... We agreed to try the CD seafood wet first and see how he does on it...
I bought some to see if he likes it and how he reacts to it... crossing my fingers all is going to be well...
I also read a lot of good reviews on Cosequin being good on preventing cystitis and UTIs, so I am going to add that to his diet as well...
I now need to work on putting Lucky on a schedule so I don't have dry food laying around and can feed them all 2 meals a day - I have some time to do that, thankfully!
Anyways... please send purrs vibes for him to continue to improve until later today (Wednesday) so we don't need to go back in.
I do not see him going to the litter box much which concerns me a little, but I think he is probably going while I am sleeping or working, and I am just not fast enough to get to him. His belly does not feel swollen or tender, and he is not showing any signs of being blocked.
As I typed this he just peed a completely normal, blood free pee for meowmy to go to bed happy! That's my boy!
I hope this is the first and the last time we go though this scary scary thing!
