Thats great news Before you know it Butter will be a regular lap warmer for everyone! There's a cat at work named Peaches who has been at the shelter for 4 years. She reminds me a lot of Butter in her personality. I've been working with her lots and have her to the point where she can spend 5 minutes in my lap purring. I do have a lot of battle wounds from when I first started working with her though Anyway, its such a great feeling to finally see them come around. You're a saint for believing in Butter and taking him under your wing.
