Sweetie Kitties were rubber/plastic long-haired toy cats that were covered with fuzzy fur. They were made by Hasbro in 1989. There were "Party Time" versions of the cats which came in unnatural cat colors such as pink, blue, and yellow and there were regular ones that came in colors such as tan, white and black.
I believe they came out after the Sweetie Pups were made, which I think was slightly amore popular line featuring dogs. It is easier to find Sweetie Pups online than it is to find Sweetie Kitties online.
