Thanks so much for all the advice - let me clarify - I meant that since the cats were here first, I'm not going to jeopardize their happiness and health for a new puppy. Of course, if I decide that a puppy will not pose a serious risk to them, I understand that he will need more than they will. In fact, the fact that my cats need so little will make it very easy for me to care for him
As to where I get my puppy from, if getting a puppy from a dear friend - a puppy whose parents I have both met and whom I have literally gotten to watch grow up from the day he was born - if the source of my puppy is going to be an issue with being in the forum, I guess that's ok. I will have to look for advice elsewhere.
Thanks again for all the advice! Happy Holidays!
