The butchering is fine, yes. I would keep everything as tidy as possible in case she couldn't handle the butchering part. I would stop, and take her inside. Probably put her in the playroom with the gate up, and finish cleaning in the kitchen. The purpose being that I am alone. If she is here, and I didn't do the deed while she was asleep, she may need to be there when I do it.Agree, dont show her the actual killing, but I think that the butchering is another thing.
What is the purposes, of showing her?
