The (not so) darling husband is taking the kids to see his sister and her partners new house at the weekend while I am working. Obviously i mustnt want to see the new house as he couldn't wait until next weekend when I'm free 
Anyway they have had a rescue cat for a couple of months who is aggressive and has attacked them more than a couple of times. (I know this as they regularly post this on fb)
He was talking to the kids tonight about how exciting it was, and I said be careful of the cat please. He rolled his eyes so I asked why, he said oh don't be stupid let them make their own mind up!
The kids are 7 and 6 and already a bit wary of animals (I try to encourage them but not force them). I am worried that this cat is going to scare them.
So was I being unreasonable to tell them to be careful and ask for them not to be left alone with the cat?
I have nothing against cats by the way, and I am fully prepared to be flamed. :o
