Thanks guys for your help she had a pain in the middle of her back the vet gave me pain meds and she got a pain shot. I think she may have pulled her back from jumping on my computer chair that swivels to get to her window perch
I know you said she has no signs of pain but maybe just certain spot that hurts only when you pick her up. I watched a show about cat behavior and the cat was fine until the person touched a sore spot on him. Maybe just let your cat do what she wants with you, rub her on the ground and watch for a certain place she doesnt like to be touched. I hope things get better for you
I wonder if she doesnt like being picked up how do you do it, sometimes it can hurt, try petting her whilst she is on the ground or a chair...pain will make animals aggressive .My cat hates being picked up so I stroke her when she is on the ground or where she is sitting ...
