So, my 4 year old cat, Indy, has been diagnosed with heart disease. It all started nearly 3 weeks ago. He became lethargic, refused to eat, and wouldn't leave his chair. A vet trip later, and they said his stomach wall was inflamed. A normal, easy to resolve problem. Well, he saw minor improvements on Cerenia but his condition began rapidly deteriorating. Last Thursday (The 13th), I took him back, assuming it was still an inflamed stomach wall. The vet then informed me that he developed a heart murmur, and requested to do blood work and x rays immediately. I gave the green light, and she gave me the bad news. Fluid on the lungs and all the other signs of heart disease. He's now on pills twice a day for the rest of his life (Speaking of that, is it alright to pill a cat while they're on their back? It's the easiest way for both me and him I think). They seem to have made him slightly more active and alert, but he still refuses to eat no matter what we try. He's losing weight, and still lethargic but slightly more active (And will purr if he sees me). We already know his condition is terminal, and 3 years is probably the most he's going to live if he responds really, really well to treatment (She said realistically, he probably won't see 2018). I'm wondering if it may be time to start talking about letting him go before it hurts him too much. I'm just not ready to let go, and never will be. I feel so much guilt that I can't afford the treatment he needs (A cardiologist, ultrasounds, more pills, etc.), but I'm also sitting here with a 4k TV and an Xbox instead of an emergency fund in case something like this happened. I can't help but feel his blood is going to inevitably be on my hands, or that I didn't love him enough to prepare financially for something like this. So, what is your experience with knowing when it's time to let them go? I'll personally never be truly ready to walk into a vet's office and tell them I want them to kill my cat, but I'd be willing to do it instead of have him suffer for my sake.
