Jewel is around 10 years old - don't know exactly because she was adopted as an adult from the humane society, but she has gotten quite a bit of grey on her snout. Lately at night when I'm up, she keeps coming up to me - not really whining, but making some kind of noise. I pet her, play with her, she has food and water, she doesn't want to go potty. Then she'll lie down about 5 feet from me and stare at me, continuing with the not-quite-whining thing. If I look at her, she comes over to me and wants me to pet her. Then she decides that she doesn't want me to pet her anymore and the cycle starts over. I can't figure out what she wants/needs. Any ideas?
