So there's this feral kitten who I've been feeding that has started to become super friendly. Every time I open the door and he's outside he tries to get in and wants attention. I know that feral kittens like this can be adopted but does anyone have experience doing so? I feel bad for the poor thing and would like it give him a nice home, especially since my older cat recently passed away and I would love to have another kitty in my life. He is friendly and likes to be pet sometimes, but I'm worried that he would have a hard time adjusting to being a housecat. He's only around 4 months old so I was hoping if I adopted him now he'd be likely to adapt well. Advice?
