so today I was out driving and came accross a cat laying on the side of the road, it's just a stray tabby cat, we took her to the vet and she has an injured leg but she is fine, it also turns out she is about 4 weeks pregnant, we brought her back home but my ragdoll is due any day to have her babies, the stray does not like my cat at all nor does my cat like this stray, they keep hissing and growling at each other & from me holding this stray cat who is actually very affectionate with me , I nOw have her scent on me, if I pat this stray cat then go anywhere near my pregnant ragdoll or touch my pregnant ragdoll she actually hisses at me & she's never ever ever done this before ever, she won't even let me near her now, I'm a bit concerned as I'm not sure whether I should let the pregnant stray stay with me or hand her in to rspca.. I'm worried that my Cleo will not let me near her now when she has her babies or if I touch her kittens when they are born and put the strays scent on the kittens I'm worried that my Cleo the ragdoll might turn on her own kittens and harm them? Is this possible? I really do not know what to do
I've attached a photo of her, she's really friendly with me
