All I can say is, "Well done, you - and good luck!!" I was adopted by a stray female cat, 7 yrs ago (we already had 2 of our own, and 3 dogs). She'd been dumped by her owners and of course, not spayed, so was pregnant. She took up residence in an old mobile home we've got and eventually gave birth to 8 (!) healthy kittens. We kept 2 of them, along with their mum and found homes for the rest. Sadly our little male kitten was killed by a feral tom cat when he was only 2yrs old, but I still have the little female and her mother (both now spayed!). The mum chose her own place to give birth, so if you have a spare room, maybe you could make a little comfy space for yours in there? Don't worry, she'll find somewhere (probably somewhere inconvenient for you, like a kitchen cupboard) and when she does go into labour, you don't need to do anything except keep an eye on her and make sure that she's managing OK. She'll know what to do. If you decide to keep her after the kittens are born, don't get her spayed until the babies are completely weaned. If you contact one of the cat protection charities, they may be able to help with the cost of spaying her, as you've kindly taken her in as a stray. Good luck!! K
