Well, it was destined to happen eventually, she really wanted to adopt him and take over the mothering... don't worry, more to you are on the way!! (of that i am sure!). Spencer will have to go back downstairs and resort to dog food--the GOOF dog!!!! Good job anyway- his umbilical cord was intact when you found him and it is always such a slim chance that they survive without mom at so young an age- someone was watching out for both of you, i'd say!!!
Kim, do try the recipe formula when you get a chance- I swear it has powers in it!!
