We recently (about 2 months ago) got a kitten. He's about 5 months old now. At the time, we were both spending a lot more time at home, playing with him and being with him in general. Now, we've both got full time jobs, so we're away on weekdays for 8 hours a day. He has tons of toys, a kitty condo to nap/scratch on and we give him access to all the rooms of the apartment (except the bathroom since he gets into the trash).
My question is is it possible for him to get too lonely and bored when he's home by himself? I wouldn't want him to be too unhappy or upset that he's alone most of the time, because he's very friendly and generally loves attention from us.
