Hi guys (and ladies), sorry I've been a little MIA this week..

Hi guys (and ladies), sorry I've been a little MIA this week. For starters Monday and part of Tuesday there was an Internet outage in my area that lasted 30+ hours. I was not happy to say the least. I don't mind using my phone for OnlyFans, but I do depend on my computer for 50% of my work. Then, far more upsetting late last Friday night one of my 6 indoor cats became very very ill. He's at least 16 yrs old so I was concerned, but also thinking since he's old and has never been exceedingly healthy, well maybe this what his ending is going to be like. I did think his symptoms were really odd though, he was throwing-up, retching loudly, and slobbering profusely. He almost seemed like a zombie, he was totally out of it. Of course, I called my vet and a friend of mine who is a vet, and they both said to watch him and if he gets worse my only option would be to take him to the emergency animal hospital that is open 24 hours a day, otherwise I could bring him in on Monday. So, fast forward to Sunday night and low and behold another one of my cats gets the same exact symptoms, and is extremely ill. He's vomiting, retching loudly, dripping at the mouth and staring into space like he's out of his mind. And this cat is 12 yrs old and has never ever been sick even once, he was a picture of health. So, Monday I take them into the vet, and everyone agrees they have gotten into something, like perhaps some type of poison. Now that 2 of them are exhibiting the same bizarre symptoms we know it's not a natural disease. The 1st thing the vet asks is if they have possibly eaten rat poison. No, no absolutely not. I have nothing like that in my household. No plants, no dangerous chemicals, they have not eaten flea/tick medication, chocolate, medicine or anything else. They do not have access to anything that could harm them. These 2 cats have never been outside and they just lay around all day on their cat tree or bed - that is their cushiony life in a nutshell. Anyway, the vet gave them fluids and some antibiotics, but she said she has no idea what's wrong with them, other than she acknowledges they have ingested some type of toxin and they are very very sick. I spent time today calling other vets and talk to their vet about this situation. Tomorrow (Thursday) I have another vet coming here to examine them to see if she can figure anything out. The current vet jumps to "euthanasia" as the cure all answer to this problem, which I politely told her to fuck off, because I am going to give them the best chance of making a comeback. It hasn't even been a week! I don't consider any of my animals to be disposable, and I believe animals can do amazing things include coming back from the brink of death. Cats are tough, they are survivors. Their blooodwork did not show organ failure or even poor values, so we will continue rooting for these 2 boys to make a swift turn for the better. I see some slight improvement from yesterday, it is very slight, but it's definitely better. I am still so puzzled about how this has happened... My brain is working overtime thinking of every possibility and I keep ruling out literally every one of these potentials. Fortunately, my other indoor cats are fine, they seem completely unfazed and 100% fine. So, the million dollar question is how did only 2 of my cats come in contact with a toxin when they all live in the same house and eat the same food??? Any thoughts? Any good detectives out there? The only thing I have remotely considered was those 2 shared a mouse that had been poisoned at a nearby house. But that seems weak, because I don't live close to anyone. How long can a mouse travel while being poisoned? My nearest neighbors are a good distance from me, it would be a very long walk for a poisoned mouse.
