On January 13, 1991 at the Friends of Animals Spay and Neuter Clinic, my cat Olga, was spayed, The vet told me that she had been pregnant, but that "we took care of that"
I did not want any more cats, so I approved. Olga was my faithful kittycat for the next 15 years, until she was run over by an idiot in a Cadillac that a neighbor said swerved on purpose to hit her. I buried her under a tree in my front yard. She liked to shed on my black and whir clothing, because she was gray and could make a mark either way. She preferred Meow Mix.
There was no written record other than a cancelled check to the clinic for $20 which I threw away.
