welcome to the wonderful world of KittyCatS!
1. yes they do grow daily. from day one to 4 you can "attach" them via their menu if you want to "wear" them on your shoulders, from day 5 on you can hold them .
2 & 3 turn breeding back on, as it takes 7 days when you turn it on to get them to start to gain love. they can start to gain love on day 7, so if you want to breed them turn it back on asap
4. wherever you rez them or move them and set their "Home" will be where they go to sleep!

this makes for fun and creative sleeping arrangements. you can make your own bed, have them sleep on a sofa, chair, tv, whatever YOU want
hope that helps and feel free to join our KittyCats Addicts group to ask questions in chat, you will find we're a really helpful and fun community.
welcome again!
