I can usually understand what's going on with my kitties, but this problem baffles me. My eldest cat of three, Loxy, has always been quite a talkative cat, and the least affectionate out of the other two (but never refused affection). As of lately, however, she has been restlessly running around the house, meowing (not low pitched...actually in the normal/high range) sometimes at us, but mostly out the window. The weird thing that I noticed is that she only does this at night, and when we try to calm her down by petting her, she runs away. We've thought about getting something to take her outside with (we live in an apartment complex), but decided that might not be a good idea because with the way she is, she'd only want to be outside more often and it would make things worse. We also thought she might be feeling a little anxious or crowded with the other two cats around. We don't have a really big place, but are moving into a bigger place soon. When she gets this way, she avoids contact with the other two cats, but during the day, she is completely normal. I love my cat and I hate to see her this way, and she's also doing it while we sleep, and it keeps us up! If anyone has any thoughts or suggestions, please let me know! Thank you so much!
