So that feels-laden comic about the “ugly” cat getting adopted by the older gentleman is called Ojisama to Neko. As far as I can tell, Ojisama to Neko is an ongoing online comic that’s mostly posted to the artist’s twitter account, @sakurai_umi_. You can even see the original of the adoption comic.
A physical manga is going to be released on February 22nd, which is Cat Day in Japan. Until then (and until we get a translated version) you can see lots more of them here.
The weirdest part about the Ms. M&M post is if you google “Bambi Ps2” you get an entire fanon wiki for a PS2 Bambi game that doesn’t exist and is entirely made up, including list of bugs and glitches that don’t actually exist, because there isn’t an actual Bambi game for PlayStation 2 or any Bambi game at all for that matter
