So far we've tried:
Boost (phytopet) - a herbal remedy recommended by a lady in the petshop she used on a cat that was unsettled frequently.
Rescue Remedy - another herbal remedy, that seems to work sporadically.
Feliway spray (Thanks Ruth!) - that works for a couple of days as far sa I can tell. I think the next step is to save for a diffuser.
Oh, and ear plugs don't work. She's LOUD!
You're right, though. The preferred time to wail is apparantly around 4 in the morning. (It's a symptom of senility, the bodyclock gets messed so I'm told!)
She gets cuddled a lot, and sometimes that helps, but sometimes she'll still be crying while settling on my knee!
