Hi All. I am brand new here, and stumbled upon your site multiple times in the last week and a half in my relentless Google searches trying to find possible explanations for my baby girl's symptoms. This is veryyyyyyy long because I was trying to be as thorough as possible with the details so that hopefully someone may have some suggestions. My girl is 9, going to be 10 at the end of the year (Christmas Eve baby). She is a short hair gray tabby and has been relatively healthy her whole life. She did have surgery in 2012 for a condition called Entropion, but she recovered well and has only had to have minimal doses of steroids (very infrequently) when her allergies flare up so she doesn’t rub her eyes raw but has not had any in well over 8 months. She’s also been overweight half her life despite being on diet food for YEARS. About two years ago, she had the first few “episodes”, which the current thought is she’s had/has absence seizures. There have been a total of maybe 6-8 over the last two years, and I think I linked it to a B&BW air freshner that has clove in it, because all of them happened around the same time I used that particular scent. It was plugged in on my side of the bed for fall/winter months and she sleeps on my pillow all night every night, so the vet thinks that’s why she had reactions and my other cat didn’t (he does not sleep with me). We immediately stopped use of ALL fresheners in our home and everything was normal for a few months… then in May she had another episode. This time she was fully alert, but when she tried to move, she could not move her front legs. She was basically pushing herself across the room with her back legs and you could see terror in her eyes. Her front legs were bent up by her face and were stiff (we tried to move them gently). I cried for hours and the next day we took her to the vet. The vet thought she might have HCM so promptly did a proBNP test which came back completely normal. We brought her to a neurologist that week, who did an exam of her and said she showed nothing immediately alarming He suggested some tests (radiographs, MRI, spinal tap, etc) but then basically talked us out of them because her symptoms are so infrequent. To our knowledge, she’s been fine since that time (first week of June). Two Sundays ago (9/16), she threw up 3 times after eating her dinner (within about 15 minutes) and I noticed she kept was having almost like a hiccup motion in her body (no sounds or reaction from her mouth, but the best I can explain is it looked like hiccups) and the hiccups happened randomly for a couple of days (no further vomiting). Around 1:30am on 9/21 I woke up to her meowing on my pillow, when I reached out I realized her head was moving side to side like a bobblehead. She was completely aware of me and her surroundings, but she was purring constantly she kept meowing at me like she wanted me to pet her (Even though I was). This lasted maybe 3-5 minutes. We sat up with her for an hour and she was her normal self…. after arguing with myself, decided against the emergency vet. We took her to her normal vet that afternoon and they said it sounded like tremors, and ran bloodwork, her ALT came back at 488. They immediately started her on IV fluids for 3 hours until they closed and arranged to have us transfer her to the emergency vet (same place the neurologist works at). By the time we got to the emergency vet (45 minutes), they said she was showing signs of fluid overload. Her nose was dripping, her breathing was awful, her oxygenation level was low (93 I think), and had a fever well over 103. They did NOT put her back on fluids, but put her in an oxygen cage overnight in the ICU. While she was there, they did chest/abdomen radiographs (there were a few spots in her chest but it was not fluid and not distinct enough to be masses, so they are not concerned, don’t think it’s anything). They also did an echo, which came back perfectly normal, and a full abdominal ultrasound which showed nothing visibly wrong with her liver, or any other of her organs. All of her other bloodwork was normal except ALT was 475 Saturday afternoon (Down from 488 Friday night), and ALKP was 138. The critical care vet said based on all of that, her opinion is that she must have had seizure activity that caused her to be hypoxic and therefore elevated her enzymes. She showed no seizure activity while in the hospital, and after tests came back and she was stable, we took her home Saturday night. Tuesday evening we brought her back to her normal vet for a recheck, and her ALT level was 405. The vet said she would have expected it to drop MUCH more but was happy to see at least very mild improvement. We scheduled for another recheck in two weeks on 10/12. The following day, her regular vet called me to follow up and said she had a nightmare about my girl, and she personally called the neuro we saw in May and explained it all to him… at which point he said he is “intrigued” by her symptoms, which I feel cannot be good because that means they are unusual. He said it was VERY VERY unlikely that seizure activity caused the elevated ALT and based on all the data, thinks she may actually have an arrhythmia and wants her tested for that. Also he said the hiccups could be a form of seizure activity, but he has never seen that, so could not confirm. So per my vet, I called immediately to get her put on pet insurance before any further tests or diagnoses, but it’s a 30 day waiting period so we are just holding our breath and watching her like a hawk to make sure she is stable enough to wait that long. If she declines I will of course bring her sooner, but I am trying to not overreact. Oh and it was determined she did NOT have fluid overload,…and her current vet thinks she had a reaction to the Convenia. She had one other cat who had the same type of symptoms (breathing, fever, nose drip, etc) in the past, so she’s flagged her file to never use that drug on her again. The only treatment is right now she is on day 5 of a 30 day course of Denamarin for her liver. After tons of reading, I am wondering if maybe she has hyperthyroidism? For some reason I was thinking they said her thyroid was fine, but in all the results over the last year, I don’t see where her T4 has ever been tested (unless it correlates with other values), so I think maybe I made that up? But I’d think that would be something they would try to rule out first especially since she’s almost 10. She is NOT diabetic, her kidneys are fine, she is NOT in liver failure. She grooms herself as much as ever, she could eat all day long (always has been that way), but she has lost like 2.5 pounds since May and is around 13.3 now despite having a full appetite. So she’s definitely not underweight, but that seems like a substantial drop. Litterbox habits are normal, drinking is normal. When we go back in two weeks to re-test the ALTs, I am planning to ask if they can also test her thyroid just for peace of mind. Also planning to bring her in for monitoring for possible arrhythmia after the 30 day waiting period for her insurance. Has anyone else experienced these symptoms in their fur-baby, and what was wrong? Since she’s eating as much as ever and is grooming herself, we are confident she has a lot of live left in her but so far the only answers have been no answers and I am having trouble accepting that, just waiting for another shoe to drop. So sorry for the length – I promise I really did try to edit it down but it just all seems potentially relevant. I have all the bloodwork values and discharge papers if there is anything else that may be helpful to know.
