The Tasmanian Devil and the Tasmanian She-Devil are brown furred and look nothing like real Tasmanian Devils, which have black fur.
The Roadrunner also looks nothing like its real-world counterpart. Roadrunners aren't bright purple/blue nor are they the same size as a coyote.

Calhoun Capybara from the same episode actually looks more like a wombat than an actual capybara.
Arthur Read and his relatives are aardvarks, but aren't readily identifiable as such. Real aardvarks have giant noses that stick out. Arthur, D.W., and other Reads have no nose. Averted in the early books, in which Arthur's enormous nose is actually the driving force of the plot.
Notably, there was an old CBBC puppet mascot called Otis The Aardvark, who looked more like an aarvark than Arthur ever did. The original Arthur's nose points downward, whereas Otis' nose sticks straight out like that of a real aardvark.

Daggett and Norbert from The Angry Beavers don't look an awful lot like beavers, even though they do have flat tails. This is constantly pointed out in the show, as most people assume that they are weasels.

Cyrill Sneer and his son Cedric on The Raccoons are suposed to be aardvarks, but have pink fur and snouts that bend down. The show's creator did this on purpose so kids don't think that real aardvarks are greedy industrialists.
Stitch himself is described as being a dog, but he actually looks more like a mutant koala instead, as pointed out by Nani about halfway through his film.
Though unlike other examples Stitch isn't actually intended by the creators to be a dog. Which is good considering his default form has six limbs, antennae, and dorsal spines.

And Eileen looks more like a midget human with three pointy toes on her feet and a tail than a mole.
That ostrich and possum in "Replaced". The ostrich looks like a duck. The possum...well, he may just be the technical "possum" (the one that lives in Australia).

Horace Horsecollar is supposed to be a horse, but looks more like Goofy (whose species is ambiguous) than anything else.
Steggy from the Chip 'n Dale Rescue Rangers episode "Prehysterical Pet" is supposed to be an alien Stegosaurus, but he looks more like a lizard with backplates and a spiked tail instead.
Most of the My Little Pony: Friendship Is Magic characters just barely resemble ponies, instead looking more like mutated toy-breed dogs with cat ears. While male ponies have muzzles that have some semblance of a real horse's muzzle shape, female ponies have muzzles shaped more like that that of mouse lemurs and galagos (or bushbabies). However, this makes them lookadorable.
Louis from Foofur is supposed to be a bulldog, but while his face and ears are like those of a real bulldog, his big bulky body would suggest otherwise.

Sam the Sloth from the Timon & Pumbaa episode "Hakuna Matata U." looks more like a bear-monkey thing than a sloth.
The characters in Out There are human (by extension of background elements depicting humans and referring to humans as themselves) but they don't look too human at all, in fact most are fairly ambiguous in terms of species and the lead character Chad and his family look nothing like the others, instead being less ambiguous and looking more like very hairy rodents but still of indeterminate species and considered as part of the same species as the rest: "human".
