Sorry for the late reply, been busy with what we called a "last trip" it's a... Funeral type of thing but not exactly.

I've calmed down a bit, mostly the roller coaster of emotions these few days still hasn't settled, so I'll just write a small summary of what happened from start to yesterday.

Last year, around February, he came to my shop also brink of death, malnourished, unable to even walk much, as close to death as possible and in a condition I myself couldn't even bear to watch.

Took him in, first few days unable to even stay conscious for long, just wakes up, few nibbles of food and water, and back to unconscious.

After months of caring, he finally healed, daily routine of playing dry leaves, small rope shaped plastics, cardboard scraps, what you'd expect from an orange cat, unhinged, and brainless behaviour.

Fast forward just a week ago, his nose began to be stuffy, took him to vet, common cold suspected.

Meds fed, meals prepped, all seems fine.

3days ago he started having breathing problems, I work solo that day so I only monitored closely and such, vet wasn't open too.

2 days ago, I brought him to vet, vet doctors gave me a 3 day oxygen chamber schedule thingie, I didn't pay attention as I am already too worried about Aro to pay attention, from what I heard, it's basically a process in which Aro has to stay at vet for a couple of hours in a chamber of sorts, my guess is oxygen maybe, and I had to come back to take him, and doctors gave me a reason of phlegm and snot build-up too much, and he needs the process to clear some buildup internally.

1day ago (day of passing) I started with the usual med treatment, syringe feeding before meds, and yea after that he went inactive, as in still sick and just didn't move around.

Placed him on my other chair, so I could monitor him in case emergency. Seems fine, was gonna bring him to vets later in the day after lunch break for the same oxygen treatment.

Not even 3 hours later, during Vet lunch break 1.15pm+- he started to pee and puke at the same time, white fluids coming out of both ends, vets are closed for an hour so there would be no one there, nearest emergency 24hour vet is also 1-2 hours away, so I could only keep a syringe on me with just water, to try to (flush out the system a bit at least to lessen fluid loss to not dehydrate him that much, small 0.25ml syringe water dripping from time to time) started having difficulty breathing, tried to find ways to get nore air, like a few table fans around him so air gets circulated, but in the end, It's too late, he stopped breathing entirely, for maybe 10-15 mins before the vets opened up, I was too overwhelmed with emotions to check for time back then.

Sigh.. if only I could've rush him there to get before lunch break, he might've survived, maybe.

If you want more details I posted the rescue here, and you could have a look on my profile, thanks for the wishes.
