I had to step in and put a cat down today.

I'm an animal lover and would never hurt an animal in any way. But a few days ago my Aunt who lives next to to me told me her cat is on its last leg. And she's going to give it Tylenol to put it to sleep. I was outraged. So I looked online to understand why some people use Tylenol to put their animal to sleep. So I read that it's basically poisoning the animal. But the animal should pass away in an hour. So I didn't go back to my aunts till yesterday. She said she put the pill in water and she seams to be drinking a little here and there. I picked the kitty up, and smelled an oder. FYI if you've been around any animal who is close to a natural death, they do tend to have a smell. So I held her and told my aunt she has that smell. She said she didn't know why the cat hadn't died yet and she will put another pill in her water tonight.
I went home, and the more I thought about it the angrier I got. She should just take her to a vet and have them do it, but I know my aunt would never spend money on an animal no matter the reason. So this morning I got up and was thinking to myself why the little cat didn't already pass away. Then it dawned on me that the kitty probably isn't doing ALL the water so she's near death but not dead yet. I went over to my aunts house again the poor kitty was still alive. I picked her up and here head lulled to the side and she was so week. The smell was unimaginable. So now I'm thinking the pill was probably shutting her organs down and already starting to go septic. I was pissed.... I told my aunt what she was doing wasn't working. She said.. Oh she'll die in another day or two. I said NO I'm stopping this right now. Knowing one pill should stop her heart, I got a little gravy and smashed one whole pill in it. I put in a syringe and told the kitty it would be OK in a few minutes. So I gave her the whole pill, and continued to pet her, she was still purring. But she got very relaxed and passed away. WHY DONT PEOPKE STEP UP AND DO THE RIGHT THING. THE THING THAT NEED TI BE DONE SO ANIMALS DONT SUFFER. THE HECK OF IT ALL, I WAS THE ONE TO GET HER SPAYED WHEN SHE WAS YOUNG, AND A FEW OTHER TIMES TO A VET. I am emotional already. I have panic attacks and have clinical depression, my dads death day is the 31st of October. I don't need another reason to be upset.
Seeing the pore cat will stay with me forever. Sometimes I hate humanity. Sorry so long.
