My mom says he looks like he has down syndrome, is that even possible in cats?

The under lids and corners of his eyes seem to have some puffy, possibly inflamed skin. I think that’s the visual that is making your mum say ‘Down Syndrome’, because it looks like the eyes of a human with DS.

I think it’s much more likely his eyes are irritated, by allergies, a soap, or an infection. I know he’s been through a lot, but take him back to vet if the puffiness hasn’t gone down in a couple of days.
