Hi all. I rehomed a lovely rescue cat 18 months ago, a little two year old boy who'd been abandoned. He was pickly but very loving. But after a year he sadly was found dead by the side of the road

. Very sad but after a while the cat-shaped hole in our hous became too gaping and we rehomed a tiny very dainty lady cat of the same age who had come from a multi-cat household who couldn't cope when she had kittens. All went brilliantly and we kept her in as suggested but then she disappeared one night nearly three months ago. She is chipped and we've done the posters/leaflets and calling vets and animal search to no avail.
I've now realised that if she has been taken in by someone else they will have had my little lady for twice as long as we did so if she was discovered to be ours down the line actually it might not be kind or wise to rehome her here again....
So....in the new year I will let optimism triumph over realism and try again but I'm not sure what type of buddy to go for. My mum says that kittens are great because they imprint on you and won't roam- but then they are more prone to getting hit on the road. And an older cat will have more of a known personality and Cats Protection might be able to guide me again on one good for my situation. Quite busy road out front (they did okay me after home visit before), two children aged 4 and 5 and three by cats next door but loads of open countryside behind us and a nice garden.
Who should I look for? Any thoughts on what age and which gender might be best to avoid conflicts with the boys from next door?
Thanks in advance.
