I will have to ask my friend if the boys are neutered but Kiki is definately spayed. They are all outdoor cats, so yes they are vaccinated and would probably appreciate access to outdoors once settled.

Casper will deal with other cats just fine as he's not long ago dealt with the arrival of Zero and Kiki, and Kiki's unexpected kittens a year ago. I'm not sure about Zero and Kiki, but they're more likely to be fine with other cats rather than not, as long as they have their own space to hide.

At the moment they live with a boy who has autism, and so in that respect I think they are alright with children as long as they're not too rowdy or demanding of them. (I've never known them to bite or scratch a person for no reason)

The fostering period can be as long as you can handle, be it a few weeks til we find them another place, or a few months til January when hopefully the family should be sorted with a new home.
