I am a new pet owner, I adopted a 7 month old kitten from a rescue shelter. She is spayed and house trained, very affectionate and I think her shyness is fading. She seems to like to rub against everything. Is this normal. Also she is in one room at the moment. Should I let her roam around the entire house now. I had her for 1 1/2 weeks now. I do not know how to adjust now that I've learned she is nocturnal. What is your advice.
