Oh, another thing...not related to the food.
Everytime she plays with her toys she starts meowing like she's calling other cats; probably because she would have playtime with the other cats at the shelter plus she was a mom and one of her kitties was there for adoption too. I play with her but she's still looking desperately for other cats. I think she can smell my friend's cat that we had here recently. It breaks my heart but I can't get another cat for her (I'm lucky I was able to get her to begin with). What else should I do to comfort her?
