Hey there;
We don't have any pure black cats with a bobtail edit as far as I can remember, but this one comes somewhat close, perhaps
It's from Christmas 2020.
Other than that, I guess you could try using a long-tailed black cat, and positioning items on it to make the tail look bobbed? Scenery items that are positioned to cover up the tail may be the most sneaky, haha.
Examples of regular black cats include the one from June 2013, CS Birthday 2010, and the warrior cat Hollyleaf from February 2009.
