Short version is we are cat people. Previous cat been missing for more than a month so not looking good 
Friend has a kitten (rescued) ready to rehome and offered it to us.
We've also got a 4 and 1yo who were very good with previous cat but haven't lived with a kitten before. I'm a SAHP, so we're home a lot.
We were thinking of using a crate and room divider/stairgates to ensure kitty can be kept separate from kids if necessary (ie, when I need the loo/cooking etc!)
If our old cat came back we would keep both.
He's a lovely cat and I would be very happy to give him a home, but I'm not sure if we would be taking on too much right now.
