Cats are the greatest manipulators!!!
For a couple of years I couldnt keep my cat Basti with me so she went to live with my father in the countryside. And then one summer she just dissappeared, but my father was too scared to tell me that, lol, so he only told me when she returned!!!!!
He later heard that she had "Adopted" another family, in a house about a km away, he lives in a village and the person who was "adopted" just happened to run into dad and they began talking and well....
Cats are such opportunists, like - Ooh, this house looks good...they give me better food than the other place!!!!!lol

For your sake I hope the kitten returns Tina, but if she gets better food anywhere else, it may not....
