My cat died today. Early in the morning he started yelling in pain and then we noticed he was breathing heavily. We immediately took him to an emergency vet. While he was there, he stopped being able to breathe without assistance. Congenital heart failure. We decided to have him put down peacefully. I know he was sedated, but watching him choke on the fluid in his lungs broke me. Pink fluid slowly pulsed into his breathing tube as he left this world.
He was my best friend. We've got four cats and he was the best friend of the other three. He never hissed. He never growled. I loved him so much and I feel so empty without him around. His favorite thing to do was to slam his body into your legs to show his affection. When all the other cats were asleep in other rooms, he'd come up on the couch and cuddle with me. One of our other cats is disabled and he always made sure she was clean and warm. One of the other cats is afraid to eat alone, but he always made sure to stand right next to her at breakfast and dinner time until she was done.
No one has to respond to this, I just needed to write out why he was so lovely. There was no creature in this world as pure as him. He was such a good boy and I love him and I miss him and I don't know what I'm going to do other than roll up into a ball and cry with my partner.
Nothing anyone says is going to make you feel better, but you sound like a great pet parent and you did the right thing. I'm sure your little guy loved you as much as you loved him. I'm really sorry.
I got an old cat myself that I love to death. This post really hits home. I'm so sorry for your loss comrade.
