Cats can live a long time with leukemia. I had a cat named Max who had it and thus was a carrier. He lived to be 15 years old. Cancer in his abdomen is what killed him in the end. He was a really good kitty. He was my King of the Cats all the years that he lived. I miss him.
We also always had cats!! 1 of them died by cancer, others got killed by cars on the highway. We decided not to take anymore cats when living in front of the highway. Now we're moved and we're having two cats. one is only whining and meowing.. It's really really old kitty.. ( both females )
How old is really, really old? Over 15? My oldest cat lived to be 23 1/2 years old.
I have a cat that meows constantly, too. Nasim. What a brat. He's just like Nasim the person. Ha!
