i just started fostering a queen and her 4 week old kittens. When we first put her in a separate room she heard our cat meow and became panicked and tried to lunge out so I closed the door and she bit me on my forearm pretty deep. I didn't react while bleeding a bit and talked softly, got down low and she came over purred and head butted me. She let her kittens climb on my lap and nursed the one kitten who hasn't been weaned and slept in front of me. The next morning I was able to feed her and them and change litter, but when I picked up the old litter to take out she she yowled, lunged, took hold and bit me on my leg. Again, I tried talking softly and then slowly walked out. The third time I slowly opened the door and she was waiting, smelling and yowling, eyes wide open looking at me intently and my hand so I put the food in front and she ate quickly while growling. I didn't try to go in because she seems agitated and I wanted to give her time. Tonight I put on double layers and gloves and sneakers since she's bitten me everywhere. She grabbed hold and it and scratched my hand but the glove protected me. I sat down quietly against the door and she still circled me, but the kittens got in front of her and she eventually backed away and the tiny one that I was concerned for because it hasn't been weened and is tiny came to feed and she closed her eyes for ten minutes, but as I slowly tried to walk out she again yowled and tried to go after, but I slowly closed the door. It's almost like a blind fury which I understand because she's being protective, but it seems like she's getting more aggressive. Where she was first fine to let me in and do what I needed to clean the food, water and litter and let her babies on top of me, now she seems to not want me to even come in. What can I do to help her trust me? I would leave her be, but I want to change the litter, water and food and she's not trying to let me near. I also wanted to help socialize the kittens who are super playful and rambunctious, except the tiny one who seems to still be figuring things out. I've fostered a pregnant cat that gave birth and other cats and kittens, but never a nursing mother who's kittens are slightly older. Any advice how to help her and me?
