(sorry for the quality, my mum took the video while me and my sister were at work), like the title says, my baby Indi (short of Indiana) crossed the rainbows bridge 3 years ago, and now we only have her sister Penny + 2 other girls (Blanquita and Merlina), but every once in a while Penny will begin meowing like that on places Indi liked to lay, sleep, etc.

Is it maybe because she misses him?
