Bought Ariel a flea collar. She's noticably scratching less, plus the scabs are vanishing. I reckon it's working. Bought some flea-spot liquid, but it's cats one year and above, so the collar will have to do.
Current habits: pouncing / climbing / following feet at every step so you have to walk super slowly in case she is next to / under your feet.
Speedily leaping onto things that 5 weeks ago were the equivalent height of terrifying mountains e.g. the sofa.
Accelrating really quickly then not knowing quit what to do and bonking into the wall as if in a Tom & Jerry cartoon.
