The terrible twosome have a typical love hate sibling relationship. Occasional fisticuffs but no actual fighting. Fatty has been picking fights with poor Snorg since yesterday with proper hissing. Chasing after her to have a swipe at her. Fatty is being very affectionate and squawking at me like she used to but hasn't done recently. She has seemed quite stressed the last couple of weeks so have had pet remedy on. Any ideas about what's upset her?
