I (perhaps stupidly) starting feeding a stray that was hanging around our porch. She is now pregnant and I'm guessing going to deliver soon. When she went into heat the first time (which was a completely new experience to me) I immediately contacted local TNR places, since I didn't even know what sex she was until that point; however, she is not friendly enough to handle and now she's gotten downright nasty - she hisses and backs away pretty much every time I go on the porch, All the advice I see about dealing with pregnant ferals says "get her to the vet." I can't - I can't handle her, the local TNR place said I was on their list (but now it's much too late for this litter), and my husband is highly allergic so even if we could get her in the house, we can't. So finally to my question: what do I do with a pregnant aggressive stray on a concrete porch in February? I'm in the Mid-Atlantic; it gets pretty cold and we do have a shelter made from a tote with straw bedding. Do I wait until she's had the kittens and then try to get them to a shelter? Do I let nature take its course? Do I try to trap her after the birth? I don't want to keep repeating this scenario; I'd just as soon get her to a shelter as well, but no one will want her. I don't mind feeding one stray but if she's going to stay I'm going to have to trap and spay her. Any advice would be appreciated - thanks!
