Hi and welcome Lizzielou!

We are glad to meet you and Tito!

There will be people here who have more experience with multi-cat households but I think it shouldn't be a problem to introduce a second kitty in your household. I doubt that an 11 week old kitten can have developped his personaity so fully that you can say whether he is good or bad with other cats.

Tito should be young enough now to cope with another kitten- who should be younger than him. I recommend a boy because boys seem to be a little easier together than girls.

Take your time for the introduction period- it would be good to keep the newbie in a spare room for some time and slowly exchange textiles etc. so that they can get used to the smell of the other.

Regarding the fact that Tito is quite young there is hope that they may have lots of fun together and will anyway be less bored.

However patience is needed: I introduced my Filou and Tigris to each other when they were 13 and 16 weeks old: they fully ignored each other for a week! I began to be desperate when they started to hiss and growl at each other. A day later they slept together in one basket. Until they were a year old they were the best friends, then they started again to be distanced and now there is love, there is struggle, there is fun and there are arguments
