Thank you - and you hit the nail on the head about how I'm feeling this morning. I'm not feeling as chipper as I was last night before I went to bed and posted here. I'm going to call my vet today and try and speak with them about what, if anything, I should and can do moving forward, instead of just waiting for this to come up again. I was given some literature to read, and evidently, the next two weeks are critical, meaning the odds are high he'll block again in this two week period - although it can happen a month from now or a year from now, too. I would rather he be taken care of in the normal course of care versus an all out, "he might die, emergency" type of thing - if that's even possible. Certainly, the heart murmur is a concern and possible kidney damage. I think I'm asking the impossible as there is no crystal ball! On a practical note, I want to avoid having to take him to my current vet, as they'll want to run a bunch of necessary tests that the vet I'll eventually take him to will want to run on their own, but I don't have a relationship with this new vet, so I just need some guidance. Also, at the ER hospital, they just talk about keeping him calm, as if he is high strung, which I don't see in this cat. The literature was really revealing there, too, so I'm concerned that stressing him out and taking him to a vet right now would not be a good thing for him overall.
My husband is going to wish he stayed in bed, once I start peppering him with everything I've been thinking about since I got up! He is definitely NOT a morning person!
