I tried too look for this on the site before i started a new thread but...i got bored. My kitten is about 6 months(shes not 6 months but shes getting there) My boyfriend has a one year old cat name Kid and they are the best of friends. I take her over to visit all the time, so that she has another cat to play with and shes not bored. Recently i noticed her fur "standing on edge" i cant really explain it but she could be off doing nothing, just walking around and all of a sudden her tail doubles in size. Since i've never owned a cat before i bought a bunch of books on cat care and one book mentioned how cats would do this when they're scared or trying to scare someone off. The thing is, NOTHING is there. Is there a reason for this happening? Im just wondering if somethings wrong with her, but it looks really cute >_<
