I would appreciate advice. A couple in my neighborhood had to foreclose and cruelly put out a 2 month old kitten. I received a call about her because I try to do as much rescue work as possible. I found the kitten, with respiratory infection and very swollen front left leg. My vet treated the respiratory infection but said her leg was developing gangrene from a bad cut. He amputated and I now have Ava home with me.. She is the sweetest kitten and has adjusted well except she cannot jump onto my sofa or bed without my picking her up. That's fine but during the day, she loves to sleep on the sofa. I pick her up but she cannot get down. She can't land on one front leg, so I put her down. When I have to go out I leave her in a kitty cushion but she's not happy. I come home and she's sitting in front of sofa. Any thoughts that would help. Thanks.
