Calico kittens & cats in Salem, Missouri

I'm a property manager for multiple locations and all to often people leave behind their pets. These two sweethearts, are the babies to a calico female that was left behind and pregnant when I found her and her sister scared and in a closet hungry. The momma and her sister are bonded and also available. But these two here, are just about 4 months old. I've had no luck finding a good hone for them and I have cats, so am unable to keep them. They've never been outside, except in a catio that I have on my porch that they can go in and out of freely from my kitchen. They're great with other cats and have been around children as young as 2. I'd love to see them go together cause they're inseparable at home, but understand that may not be an option. I just want a good loving home for them as I've grown to love them myself
