I just adopted a cat from the shelter a few days ago and I have some questions. 1) My cat keeps throwing litter on the floor every time she uses the bathroom. She's doing it unintentionally but what can I do to lessen the mess or is there a good type of litter I can use (I use Fresh Step, I''m guessing not the best). 2) She's starting to claw my bed. I'm getting a scratching post soon. I'm afraid she won't use it right away. What's a good way to attract her to it? 3) She has gotten very clingy. Will she become more independent later?
