My husband and I had two cats Lacey 10 and Beemer 3. We have recently separated and I have moved from our home to an apartment. Lacey was my cat prior to the marriage and I have taken her with me. Beemer stayed behind with "Dad", part of the agreement. When I'm home Lacey seems happy. She is eating, using the litter box, purring, looking for me to pet her, and still sleeping with me. When I first arrive home though she is hiding under my bed or in a closet. She used to greet me at the door. I fear that she is spending 12 hours a day under my bed. Is there anything I can do to ease her anxiety? Should I get her a buddy? If so, how old?
