Over the next few weeks I'm going to compile a list of all the edits I know of and post them here.
The following is only a start - there's more to come ^-^

In the scene where Maddog and Dumptruck are beratting Baloo for the parrot, a couple of seconds are cut where Maddog points a gun directly at Baloo's nose.

When Kit (dressed as a seal) is discovered, a couple of seconds are cut where Seymore lasso's Kit's neck and drags him away.

When Karnage snatches the Idol from the Professor, and the professor warns his that the idol can 'Steal your very soul and switch it with another', Karnage replies with the (cut) line:

Karnage: "Who cares about that? I just want the jewels!"

I have no idea why this line was cut out...

Near the end, where Baloo climbs onto the rocket, a couple of seconds are cut where he strikes a match and ingites the fuse before he blasts off.

When Baloo and Oscar are aboad the Vulture, and Baloo sneaks off with a handful of dynamite to rescue Kit and Wildcat, a couple of seconds are cut where Oscar calls after Baloo, trying to warn him that he forgot the matches.
