DANG you did a good job with the opening for the Loud House on Cartoon Network! My friend did something similar to it on his YouTube channel before, but his account got terminated though. But I got the video, that I can send it to you, if you want.
Haha, that was awesome! Even going so far as to make it look like an old VHS recording, now that's amazing.
If TLH was a 90s cartoon, no doubt it would have been on Cartoon Network, since Chris Savino was working for them at the time on Dexter and Powerpuff Girls. He did, actually, have a CN pilot in 2000 about a cat and dog that were adopted by an overly stereotypical Italian mother - there was even a version of it with that "textured" look like TLH has.
If the pilot your talking about is "Foe Paws," then your actually right, it does have that Loud House feel, even though it's a pilot from the early 2000s. But if TLH was a 90s cartoon, then it should of been at Cartoon Network first, since Chris Savino was working over there first, but if CN doesn't like that much, then the show might head to Nickelodeon next, and the rest is history.
