LBK, little black kitty.
Many years ago, our family cat had ANOTHER litter and we kept two of the kittens. One, a beautiful black kitty with a single white slash on his chest and a sudden crook at the end of his tail.
I couldn't come up with a name for him and we all called him the little black kitty, which evolved into LBK. He grew into a beautiful, long, muscular cat. Looked like a little puma when he stretched and bared his teeth. But he was a sweetheart. And a thief. Nerf balls started mysteriously showing up all around our house. The hand-held size. I personally saw him race into our garage one day with one in his mouth!
Apparently he was not just nonchalantly cruising the neighborhood, he was on the prowl! For Nerf balls! He could not resist them for some reason. I returned a few when I could. He looked so big and mean, but he was a sweetie, loved to curl up with me and sleep. One morning, before he was two yrs old, he dragged his body to me, couldn't stand up. I grabbed him up and raced to the vet, The same vet who had fixed and inoculated him. They came out a few minutes later and said.. you know what they said...feline leukemia. I said fix him, now. They looked at me sadly and said ok.
Another twenty minutes and they came out and said he was gone. To this day, I doubt they tried to do anything, what could they have done? There is an inoculation, but no cure. I don't know how he got it and his sister lived for years afterwards.
Before the morning he dragged himself to me, there were no symptoms I noticed. He was fine, lying in the grass, jumping at shadows, stealing balls, lol. But, get the shot for your cat, can't hurt. I will never advocate keeping your cat indoors if you live in a traffic safe area. Quality of life versus quantity, he was so happy exploring and "collecting" his Nerf balls. What a great, beautiful cat.
