Just to start off, we are working closely with a vet -Booth has been in twice in the last week- and I'm mainly posting for fresh ideas/support. He's also scheduled to go back in tomorrow, for more tests, if he hasn't perked up significantly by then.
The cat in question is almost 3 (birthday is May 27), Domestic Longhair (seems to be some kind of Siamese/Maine Coon mix, if someone had to guess), male, was fixed at 7 months (found him in the forest by himself when he was 5 weeks), is generally VERY active+playful+happy, usually very exuberant. He is a slight bit neurotic - collects things, eats paper when he can, etc, but nothing really terrible. Indoor only.
He eats Wellness wet food and Before Grain dry food (I would ideally have him on an all wet diet but he gets really "bite-y" sans dry food so I have him on the dry food with the highest meat content I could find).
Basically, last Tuesday he was acting sort of "off." His stomach felt bloated (he would meow if you poked it), he was acting a bit sleepy but he was fighting it, and he was throwing up A LOT. I initially just thought they were hairballs, since little hair clumps were coming up each time, but after the 5th or 6th time, a hairball was obviously not the issue.
Anyway, we rushed him to the emergency vet where they took xrays, did some bloodwork, diagnosed him with severe constipation, then gave him an enema, a shot of 10-day antibiotics, an anti-nausea drug, and sub-q fluids.
He subsequently de-constipated himself and we went home.
The next day he was feeling better, though not back to his normal self. The next day showed no improvement or decline, but he did barf/cough up a LARGE hairball. THEN on Friday, he began acting really out of it again. He had not gone #2 since Tuesday night/Wednesday morning so I called our normal vet and set up an appt for yesterday morning.
I also noticed that he really has not groomed himself since Monday (pre-constipation). He's usually VERY fastidious. Now he might lick his paw a few times or lick his shoulder, but that's it. No "real" cleaning.
Friday evening/afternoon he also stopped really eating. Usually he's a freaking chow hound and will eat his entire portion of food in a matter of seconds but he barely touched his meal (about 1/3 the amount I usually feed him).
Overnight he went #2 (looked normal, but small) but he was even more out of it yesterday. So we still took him in.
He got a full examine yesterday, more anti-nausea (in case that would help with his appetite) stuff, and more sub-q fluids (he's been going #1 just fine this whole time, they just wanted to make sure he stays hydrated with whatever is going on). They couldn't find anything obviously wrong with him during the physical exam.
He was perkier when we got him home from the vet but soon went back to "bump on a log"-mode. Usually he's VERY interested in everything, always on the move, but right now his M-O is basically "sit in one spot, maybe purr if a human pets him, collapse into the arms of anyone who wants to hold him" etc.
And he's still not eating great. He'll eat maybe a lick of wet food and a few kibbles but no real "meal". He'll act interested in food, then sniff it/lick it, eat a little, then leave. He will eat lunch meat so I've been giving him a small bite of lunch meat with probiotics inside, hoping that maybe his gut just needs some help... I only started him on probiotics yesterday morning but I would have figured that they would have had an effect by now.....
Anyway, I'm just really worried.
He's basically my child (lol) and I really don't know what I would do without him.
The vet is going to do more blood tests tomorrow, if Booth hasn't come around by then, and specifically test for pancreatitis. I don't really understand how Booth could have gotten pancreatitis, if that's the case, but many of the symptoms do fit.
If anyone has any ideas, I would love to hear them! I just want him to feel better!
