My tortoiseshell is really odd. She will come upstairs for a huge love-in, strokes with purrs, meows and head butts then lead me downstairs and start behaving as though I'm a stranger who is about to kick her - she'll run away/cower/hide. This will occur moments after she couldn't get enough of the petting.
How can I get her to calm down? My vet just says that tortoiseshells are call crazy.
