Yea.... I guess I don't disagree with being friendly with your snakes in the way you describe, but the showers comment does frankly unsettle me. If your taking showers with them, are you taking cold showers, or do you subject them to hot temps that humans enjoy? I'm talking 90 degrees is a good temp here, which would be considered cool to us humans.

How do you know they enjoy the hot shower, or anything for that matter?

Are you purposely breeding these animals?

Just for the sake of the potentially gravid female and her special requirements, I would stop doing the showers and let her decide what is best for her body while she is developing and carrying the eggs. I see no harm in offering her a bowl of warm water occasionally to soak in if necessary... but for the success of carrying the eggs till laying, I would stop forcing her to do anything. You could end up hurting her or her eggs from that business.

Just my .02 cents

Edit: I would not recommend doing the hot showers with the blood at all. They have completely different requirements as far as heat goes... a bowl of water the temp of their enclosure is just fine.
