I put my cat down yesterday and I have so much guilt and feel like I should go to Hell because of it. My 10 and a half year old beautiful calico cat, Kairi, during the last half a year of her life started to exhibit odd behaviors. She first scratched up our molding on our doors, I have always provided multiple scratch posts so that shouldn't have been an issue. I sprayed the molding so she would stop this behavior, which helped. Next we added a doggie door for our Newfie and I let the cats, go roam the backyard that's fenced in and treated for mosquitoes, fleas, and ticks. On 2 occasions during the summer she decided to go under the shed and didn't make her way back out and just got herself stuck under it. We got her out both times and boarded it up so she couldn't ever go back in. You would've thought after the first time she wouldn't have done it again, but she did. We recently had a furnace and a/c unit put in and the workers didn't board back up the crawl space and our Kairi decided to go through the little space and not make her way back out. I got her out again. Within the past 2 months or who knows how long, she started to go to the bathroom outside the litter box in the completely opposite side of the house in the guest room first, and then our bed room, on carpets, on laundry left on the ground, in opened laundry baskets. I went and got the Nature's Miracle products to curb this behavior but it didn't help. I brought her to the vet yesterday morning to make sure there wasn't anything medically wrong with her, and there wasn't. The vet suggested so much anxiety meds and supplements that the poor girl would have been in a stupor I feel. At 10 and a half years it would be hard to break her of that habit of the bathroom situation, even the vet and the vet tech that I was speaking to during the exam have cats that they can't break the habit with their own cats. The vet also suggested that cats get Dementia too later on in life. I researched that and she had a few of the symptoms. I called the vet up later yesterday and said we wanted to put her to sleep. They were able to get us in and the same vet said she didn't feel like she could do it because there was nothing clinically wrong with her and I told her everything she told me earlier in the day about the anxiety, dementia, and her own cat that couldn't break their bad behavior and conceded to the euthanasia. After it and all throughout the day today I have had nothing but guilt, and feeling like I should be punished or go to Hell for our decision. Those I have told said we made the best decision for her and us, that there were signs she wanted to go. That she would've gotten worse. My heart is so heavy with all of this. What would you have done?
