Just got my [not the same] PA to plug the diffuser in and wonder whether Bubz's reaction was usual.
She'd been outside and when she came in her tail fluffed up like no-ones business and she sat glaring a "How dare you be here" at the diffuser for a few minutes. The only other time I've ever seen it big like that was after she'd been hissed at by a very disturbed cat who'd paid a fleeting visit, and before we put the throw in the washing machine.
She's lying by my monitor now but every now and then up comes her head, ears pricked forward, staring but then pretending she isnt!
PS she has just attempted to bite me and it was not a play one. Could she be reacting negatively?
