Why Do Cats Scratch When Excited. A few gentle strokes might be soothing at first, but excessive tail petting could be overstimulating or painful. Maybe you just got home from work and your pet's super excited to see you.
Another theory many cat owners have for why cats raise their hindquarters when scratched or petted on or near their preferred or favorite areas is to simply say “more please.” since your cats can’t say to you “yes, right there!” they will raise their butts to tell you that you have found the exact spot that needs scratching or feels best. It also happens when they are excited or frustrated. Like humans, your cat probably has a favorite object to scratch at home—door frame, carpet, or upholstery.
