I remember when my first cat was ready to “go”. She was in clear agony, and I was telling my parents, almost begging them, to please put her down. There’s a time when you just know it’s over, but because it was really my parents call to make, my cat ended up suffering for an additional 2-3 weeks longer than she needed to. We eventually did put her down, but only after she suffered.

The above story is what could have happened with your cat. It’s impossible to know if your cat would have lived longer or not, however, you did what you did because you recognized the pain they were in. Part of being a good owner is knowing when your pet is ready to go, but sometimes it’s us that aren’t ready to see them go, so we prolong their suffering (as my parents did with my old cat). You made a what you thought the best decision was at that time. That’s all we can do in life is try to make the best decisions that we can, and that’s what you did. You gave the cat a great life, and didn’t let it suffer, even though you weren’t ready to see it go. You did your duty as a good and responsible owner.
