I can't thank you all enough for your kind and thoughtful responses. Ditz was such a beautiful cat with a spectacular tail that she waved around with pride.

Phred, I do know that the kitties are fed in the morning and again in the evening.

I am going to be sure to let my neighbor know of the advice to not leave any food out after dark.

When Annie and Emma were kittens and would come into my yard, I put food on my patio table. One evening I looked out and so help me - there was the raccoon from hell. He was so big that he just sat on his haunches and put his paws on the table to look if there was any food. You know how cute raccoons can be - not this one - you could even see his fangs............

I stopped leaving any leftover food on the table immediately.
