of you seen either a cat, snowball or fish font. I only the the letter S as the kittens name is Snowball. I have search all my fonts and can't find anything appropriate.

By next year they will both be year old animals, and will be more grown! Guess cats and dogs cannot read, but the people in the family will appreciate the cat or dog fonts.
Perhaps the free 'Pawprint' font, posted at Designs By Cuties in the upper right corner of this screen, would work.
Or the 'Kittybet' at Jennysembroidery.com.
Or one called 'Cat' at Eddydesigns.com.
Or one called 'Doggie' in crossstitch at eddydesigns.com.
Good luck,
Jacqueline
