I was actually just going to post about my crying cat.
Every single night when we go up to bed she wanders around upstairs and just meows and meows. We just got her in October. At first I thought maybe she was hungry so I would get up and make sure she had food and water, but now I fill both right before I go upstairs. I thought maybe she was lonely, but after a while of meowing she will sleep in the bed with DH and I or one of the kids. Sometimes she will play with a toy for a few minutes and forget about the meowing, but she eventually remembers. Some nights it's just a regular continuous meowing, but other nights she is super loud when she goes into the kids' rooms trying to wake them up.
Is there something we should be doing? Occasionally, she'll hop in our bed and quiet down if we call her, but usually she just comes in and meows at us louder and then continues to wander the second floor. I would have thought if she just wanted us to stay up, she would realize after a few nights that we're not going to.

We're just not that familiar with cats-- I had one cat in my life, but he never made a sound. I'm just not sure if it's normal for a cat to meow every night for a half hour or if we're not meeting her needs.
