My 22 year old cat went from healthy to being euthanized in less than 24 hours and though my heart, head and gut told me putting him to sleep was the right thing to do, I'm now questioning my decision. He suffered a partial Saddle Thrombus (just one leg), and made it clear to me he needed help, so I took him to the vet immediately. An hour or two had passed and he was lightly using the leg, so the doctor gave him antibiotics and sent us home with pain meds and blood thinners. We got home from the vet around 6:00 PM and he was still enjoying his treats, so I had hope. By morning his breathing was short and fast though he was able to walk, so I rushed him back to the vet and she said he was in heart failure. She stabilized him on oxygen and gave him an injection of a diarrhetic to buy me an hour to make a decision. Money wasn't an issue as I'd do anything for my pets, but the doctor made it sound like he would have an uphill battle because of his age, so I decided to let him go. Even if meds could stabilize him and give us a few more weeks or months with him, I couldn't stand to think of him suffering, especially not being able to breathe. He was the nicest cat in the world, definitely a golden retriever of cats. After the oxygen and injection, he was purring again for the first time in almost 24 hours, and seemed to have bounced back, but again I realized this was purely artificial, thanks to the interventions. Anyway, I spent a few minutes with him and then proceeded with putting him to sleep... while he was feeling some relief, rather than letting him decline again. Anyway, I miss him terribly and need some reassurance that I did the right thing, and that his time was up. Money aside. Could I have gotten more time with him, without him having to suffer? I don't think it's fare to put my needs above his. It's just crazy to me that it came out of no where. Thanks for the help.
