Who Was That Vamp Again?

Hey Folks:

Like many of you, I enjoyed watching the 1980s HEATHCLIFF cartoon show while I was a kid back in the 1980s. The show actually inspired me to create my own series about a league of superhero cats - until I first got wind of THE THUNDERCATS. Well anyway, to cut to the chase, I particularly found the female alleycat known as Cleo (Riff Raff's girlfriend) to be very hot. I have a question, though.

There was one episode where Riff Raff almost fell in love with another female cat, thereby tempting him to cheat on Cleo. This new female cat had mostly dark grey fur, making her very gorgeous. With her low but feminine voice, she was very seductive. She was so good at what she did that Cleo got real jealous of her and called her a VAMP. Does anyone remember which female cat that I am talking about? Which episode of HEATHCLIFF was this? I want to see it again?

If anyone knows what I am talking about, then please let me know something as soon as possible. Thank you.
