Hi moosmum,

Thanks for the welcome, it's much appreciated. There are a couple of reasons Minny and Primmy haven't had their op; they are kept indoors always, they're both small for their age and a bit fragile in their health and it's a question of prioritisation. I'm looking after a lot of cats and it costs a fortune so I'm having to budget for the right time to get them done from their point of view and mine. I got little Primmy's three brothers neutered at the earliest opportunity a couple of months ago. It's a question of doing what one can when one can.

The particular question of length of time for heat was one I was shaky on, so thanks for the information about it lasting for up to a fortnight.
