Hey Sheena!
Sorry I didn't reply to your MSN message the other day - I leave the computer and forget to "away" my MSN.
I'm sorry to hear about your poor cat
Have you heard anything from the neighbours?
That's really irresponsible of them not have have their dog tied up/fenced in.
I know dogs can be sneaky and get out, but if you've seen if wandering around before, then obviously they're not very diligent with keeping the dog contained.
