Thank you so much for your kind post. Yes, it's VERY hard letting them go :-(. I've never had an animal make it to be this old so after 13 years they're a big part of our family ( his sister is also living ).
I will read over the sites you gave me. Do you think it would be ok for me try Dr. Shulze's products? I am familiar with his products ( and used some of them ) but never thought about using them for my animals.
