When does Heathcliff return?

The Catillac Cats characters were created by Jean Chalopin and Bruno Bianchi. Mel Blanc, who provided the voice of Heathcliff in the Ruby-Spears series, reprised his role as the titular cat. 65 half-hour episodes aired in first-run syndication in the fall of 1984. A second season of 21 episodes ran in syndication until it ended in 1988.
Each episode featured two segments, one being about Heathcliff and his friends, while the other featured The Catillac Cats. At the end of every episode, Heath or many other characters from the show would give out tips to viewers that are related to pet care.
