Hmmmmm...... sometime this summer we had two cute little kittens appear. We think a wild stray we've been feeding is the mama. Anyway, they might around 5 months old. We thought they were a boy and girl - he's obviously bigger, bigger pawed and you can see testicles. "She" is much finer boned - just like a lot of female cats. And she didn't have testicles.... until now. Or are they? It's not like his end, but there does seem to be a little sack there now. The female we have is so furry that I could never look to compare.
What do you know in your experience? Could our little female be a late blooming male?
