Even I, a Kiff and Gumball fan, notice many similarities between both shows. Unpopular opinion, but I think Kiff's second season is better and funnier than TW3OG. It's actually an underrated show overshadowed by being a cartoon comedy about animals (and looking like a mix of Family Guy, the Simpsons and I guess South Park, although the animation in general is fantastic, especially with hand-drawn animation practically dying for quite some time).
