It's the Red Cat mostly known from an obscure Sonic ROM hack... actually two

Loves Francesinha.

Adult Cat, a dwarf in terms of size, recommended height of 55cm (1'10) but can be any size you feel fits best in a given situation.

Whiskers are optional but preferred, keeps folk from confusing it with a fox / dog / bear... and if people do still confuse it for any of em, just play it out like a gag, think of the Angry Beavers running gag.

It cannot talk, only miau (preferrably through FM synthesis)
