Simon's history is available in my various posts here; Any questions, I'll try to answer, but his history is too lengthy to include here.

Within the last week, we ran a panel of bloodwork, urinalysis, and a stool sample - discovering that Simon had signs of two different kinds of crystals (which I guess makes him a FLUTD kitty?) and was dealing with Giardia. The vet assured me that this was likely the cause of many of his issues, so we set to work treating the Giardia with Flagyl and ordered Simon some Hills C/D Multicare food (which just got here today; I'll likely be asking for tips on how to switch him over in the nutrition forum soon; Vet didn't think the crystals were bad enough to require surgery). He's been on the Flagyl now for a few days and have yet to notice any improvement. He hasn't thrown up or had diarrhea, but to be fair, he hadn't really had those symptoms in several days prior to the diagnosis either (In fact, he was likely borderline constipated); He poops once a day or every other day, but I'm still having to give miralax twice a day to get him to do that much. Simon is still eating us out of house and home, up to three meals a day (he'd readily eat more, if we put another can of food down in front of him) which we were hoping would also decrease as we treated the Giardia.

The current major issue is his aggression.

Our vet had said it's likely the result of one of his current issues leading to some pain, which seemed feasible at first. However, the "attacks" have continued with no real rhyme or reason to them. My Mom finally saw one of the fits a few days ago and said herself that it was like someone flipped a switch in Simon's head from "calm" to "I'm going to kill you before you can hurt me" (During this fit, he just rolled over and started going nuts on my arm; He eventually needed scruffed and removed from the situation). Tonight was probably his worst fit; We were both calmly laying on the bed, not touching one another, when he bit at my arms a couple times. I moved my arm away from him so he wouldn't continue and would realize that this behavior wouldn't be tolerated, which just seemed to anger him further. The bites got worse, he'd latch with his teeth and start that kicking routine cats do with their toys sometimes but his claws are SHARP and were drawing blood. I finally got my arm away from him and stood up, slowly walking to the other side of the bed where I had items I could put between us if needed - but he launched himself at my face before I could stop him. Luckily it was just a minor scratch on my cheek, but I think I must have turned just in time because that claw was not far off from my eye and could have caused A LOT of damage.

My nieces and nephews - all under the age of 4 - come over often and I can't run the risk of Simon snapping and going after one of them (We keep them separated now, but I'm sure Simon can hear them from the other room. There's no way around this and them not coming over is NOT an option). I have Panic Disorder myself, which I thought was under control, but I'm almost afraid to be near Simon now, lest he have another fit or come after me in my sleep (Crating all night is no longer an option as that just stresses him out further, and now that we know he has crystals, we need to keep stress to a minimum). He's already on Prozac for separation anxiety issues (though we're not noticing any changes and it's been a couple weeks now; The vet did pre-warn us that some cats weren't helped by the Prozac, but we were hopeful). We've tried leaving the TV sound on, tried making it as quiet as possible, tried putting him in the crate and letting him have free roam, tried feeding more, distracting with play. There are no outside animals causing issues and no other animals in the house. Nothing is working to prevent or help these fits; It seems like once one starts, our only option is to let him tire himself out or to put him in a large metal dog crate and leaving the room until it passes (which, in the process, just exacerbates his separation anxiety). He's very sweet once the episodes pass, but holy cow, during an episode, he is out for blood.

I just don't know what else to do. If we do the course of flagyl, change the food, and his behavior is STILL fits of pure rage, I'm afraid the next step would be to consider euthanasia. I can't and won't live with a violent, aggressive cat at the expense of my own physical and mental health (and my Mom, who pays for most of his vet care has already said that if it keeps up, he has to go before he seriously hurts one of us).

Does anyone have any suggestions or have been through this before?

(Please no guilt tripping; I know euthanasia shouldn't be my immediate knee-jerk reaction but you'll see that I've tried everything I can, so far. Rehoming wouldn't really work out, as most people won't want to take on an aggressive, violent, often-sick cat and shelters are so full that healthy cats are being euthanized to make room. This post isn't even saying that is 100% going to happen)

Cats can bite and inflict severe lacerations, which are painful and can easily become infected. Tt’s crucial to work closely with your veterinarian to give your cat the best chance at improving.

I'm so sorry to read your nightmare story with Simon.
I don't think I can help you about the aggressive behavior. But I would like to say something on the Giardia. You're giving Simon Flagyl, as you wrote.
My kitty had Giardia herself and it took months to get rid of it. The vet prescribed a first round of Panacur back in February, but it seems it didn't work because we had to repeat the treatment a couple of months later, when, again, it didn't work, and at the ned of June/early July we're back to square one with this beast. The third round of Panacur was paired with a course of Metronidazole, along with a complete sanitization of the house for a week, every day, with quaternary ammonium cations, which I found in a pet store.
It was a hard battle, long and tiring, but I think I won. Hopefully. We haven't had any more symptoms since mid July, so I guess it's fine now.

This is to say that you can't say that Giardia has been fought off and eradicated, and if this is the reason for Simon's aggressive behavior because he feels pain in his belly, you might not fix the issue, unless you definitely get rid of that parasite in your house.

I wish you and Simon all the best!

Which is what we've been doing. When we noticed his behavior was off, I immediately contacted the vet and keep him up-to-date on Simon's issues because I'm so far out of my depth with his behavioral issues that I don't know what to do. The vet told me once with a previous cat that when I found myself thinking euthanasia, I needed to make a list of what the cat enjoyed or liked to do and when the number of days they couldn't do those things outweighed the number of days they COULD, it was a sign that it might be time. Simon's not quite there yet, but I also have to weigh the lives of the humans in the house that are affected by his aggressive behavior.

The infection risk is what frightens me, too. I clean the cuts as I get them of course, but I'm already immunocompromised due to chronic illness and my mother (who I live with and is available to help with Simon) is on blood thinners, so I have to be VERY careful as things can spiral out of control rapidly.

Antonio65 Antonio65 - that might very well still be the issue. I typed the initial post not long after his latest "fit", so things were still a bit raw, so to speak. I'm hoping we're one of the lucky ones and that this first round knocks it out, as his litterbox is a bigger covered one and Simon will only use it with a decent amount of litter (I tried decreasing the amount of litter so I didn't feel as bad about changing it out frequently and he wasn't having it :lol2: ). If it keeps it up, I'll probably wind up buying some cleaner that someone recommended on my other thread just to be safe.

I think it just gets me how the aggression comes out of nowhere. I could understand it if I was touching him or picking him up or if there was a loud, startling noise or something - but like tonight's case, it was quiet and we were laying in bed, trying to take a nap when he just went bonkers.

However, during his recent time in the crate, he managed to walk through wet litter again, so I need to dunk his paws in the bathtub to loosen the litter which I'm sure is just going to go over SWIMMINGLY (luckily he doesn't seem to mind too much as long as I'm quick and the water is warm)
