The squinting cat has quite a pointy face. Testosterone makes cats have ‘rounder’ faces; can be hard to tell on cats that were speyed quite young, but males capable of having children tend to have quite chubby cheeks. Plus, the black cat looks to be going for a nipple underneath; and of course, it’s actually present in the picture, whereas dad cats are all ‘wham bam thank you ma’am’ and will usually be miles away once children appear.

Far be it from me to assume pronouns, but that doesn’t really look like a dad cat to me…
