stillmoves its tail like its happy? like my kitten will bite /wrestle my hand and then i will grab its 2 back legs which she doesn't seem to like ... and she lets out a screech / meow like shes mad or unhappy.... then when i let her go .... she runs to the end of my bed ... pauses ... wags her tail like its normal and then pounces my hand again.... ? is this just a phase or instinct or something that shes scared cuz shes still so young..... or is it bad... I think its funny/cute but I also don't wanna ruin my relationship with my kitten if it could seriously be affecting her mentality... Im also just trying to tuffin her up a little bit. Can you share your opinions / experiences please?
