I have a crucial question about giving Valium to a feral cat.

Many times (more than 15 times over the years) I have given 20mg. Valium to feral cats so I could get them spayed; no ill effects but sleepiness. Reggie lives outside and is 14 and recently went deaf. She is also FIP+. I would like to bring her in out of the cold, into her own room away from my other healthy cats. Because of her age, is 20mg. Valium too much? I tried 10mg and it did nothing. Please help. I don't want Reggie to spend what may be her last winter out in the bitter New York cold. But I don't want to harm her either. Thank you for any advice you can give. Happy holidays to all my fellow cat lovers.....
