Hello guys. I wanted to ask you which episode is the one where Cheetara gets old quickly. I remember it since i was a child.
Chris here…
To the best of my recollection there is no episode where Cheetara ages quickly - but, there is an episode where Tygra ages quickly, and Cheetara saves the day! 
The episode is “Trouble With Time”: http://thundercatslair.org/cartoon/cartoonguide/episodeguide/troublewithtime/index.html - I reckon this is the episode you’re thinking of!
Hope that helps!
Take care…
Thank you very much Chris. As you imagine, I saw these episodes when I was 6 years old, and now I’m trying to find them again. That’s why I don’t remember them well.
