Believe it or not, Top Cat is huge in latin america, i mean HUGE. It's a cult show and it has been that way for decades. This is an Argentina-Mexico-UK production.
Seems that the mix of the latin american dub using local slang, and the love for characters that are "from the streets" is what gave the appeal to LA audiences.
This works a million times better than say, the Yogi Bear movie.
Taking an iconic 2-D character and then re-designing them with realistic fur, dilating irises, etc always baffles me.
