Dear sirs,

I have to call to your awareness of the fact that Mr. Kuklachev and
his 'Cat Circus' is arriving to SF on Dec, 20 (Presidio Middle School,
450 30th Ave., San Francisco, CA 94121) for their cruel animal public
performance and outrageous cat show.

As in most countries of the world animal circuses are banned and just
considering the possible methods one freedom-loving animal such as a
cat could be trained at all, I have to warn you about this act of
public cruelty.

Yours sincerely,
