Welcome to the forum. He's cute! I can answer the toy part, best to wait and see if he likes them.
As for the cats , most rescue profiles will say if he/ she likes them. At least, where I got my rescue indicates it. Mine has to be the only one in the home. She doesn't like cats and other dogs. Natural diva ? Lol
I love my girl wouldn't trade her for the world . I only had her going on 8 months.
I would think the organization or place would provide you all the details about your future EBD. Best to you!
