I'm sorry for your loss also. I had a male cat that was fine and one day I came home and he was dead, looked as if he had gagged a bit (wet mouth) but he was in his favorite sleeping spot and was dead. He was only about 7 years old. Weird.
Justme2, so sorry for your loss. One dumb question how many of the cats were male. We just lost 2 unrelated cats within 9 months of each other and both were male neutered cats and both saw the vet regularly. One we had inherited from my sister when she passed away. His name was Petey aka Sir Petersworth, he was about 9-10 years oldhe was a Scottish Fold , got sick quick suddenly and took him to the vet and they diagnosed him with kidney cancer and basically said ther was nothing they could do, and had to have him put down. Then our sons cat Zero aka Zman approx 6-7 years old he was your typical black panther cat with jade green eyes, suddenly started acting sick on a Monday, took him to the vets on Tuesday and they diagnosed him with a urinary tract blockage and kept him and were treating him and called us the next morning and said his vitals had dropped drastically, and he was dying and his organs were shutting down. Wife and i cried like babies as he passed away in or arms. At that point in time I said we will never own another male cat.
How old were these cats? You had one for 15 years and the others for 10 but I never saw where you said their ages. Is it possible, if they were roughly the same age, it was just a coincidence they all died around the same time? Like some old people, animals will sometimes "give up living" when their mate or companion dies.
3 Dead Cats/ Opinions Needed
Sounds like a good start
I was wondering why anyone would want three dead cats and opinions.
