Pmsfl, I always thought that too! Especially since we're not even sure if he's a stray (we think he lives with an old lady though).
But it's SOO cute, cos he comes every day and tries to see his baby! I'm not sure why, cos I thought dad animals didn't care - but he sometimes sits outside the house and wails for my cat (the mum) to come and see him, and I assume so he can see the kitten too.
But now he's started coming inside the house - and cos we're animal lovers we keep cuddling him and feeding him - so he keeps coming back, haha.
I want a family picture of them lmao!
