I originally thought my cat wanted to be an only cat. Anytime we would take her over to my in-laws to play with their cats barely younger than her she would hiss and would NOT want us to touch her. But normally by the end of the visit she acted interested in the cats and even wanted to play. We went out of town last week and they kept her at their house for 4 nights. By the time we came back her attitude towards the other cats had changed drastically and she enjoyed their company. Now since bringing her home she has acted a little differently. I wonder if she is bored? There are times when she just wants to be alone and sleep but as I type this she's trying to entertain herself with a little stick. Since the vacation, she'll now just look at me and meow like she wants something but she has food and everything. Should we get her a playmate?
