Cast Iron Sleeping Cat doorstop

This cast iron sleeping cat doorstop was given to me by a 90 year old woman who told me she had it in her family since she was a child. There are no markings on it to identify the maker but from the very few similar examples online it may be from the Albany Foundry in New York. It has green eyes,gray ears, and a white marking on its forehead. It appears to me to be in very good condition and am curious about its value and its age. 

Good
