My friend is trying to find some old stop motion cartoon, he saw it 10-12 years ago maybe it is older, but he is not sure. Movie is about anthropomorphic animals tryna to escape from kind of "epidemy" of bugs. Style of animation is kinda the same with style of "Fantastic Mr. Fox". He remembers one scene where two animals, the foxes or the cats, are in the building and there's lots of bugs flying out of the vent, they were trying to swat them all away and then somehow escaped that building. I drew that scene and he said that it looks kinda familiar, please only thing we found is mail.ru question about this film.
