Good Luck with it all. We got our first pup in July and second in October. They too want to play with the cat but he is twice their size. Wally mainly lives in the conservatory and we have kept them apart a lot apart from supervised visits. We are now making a concerted effort to bring Wally into the main house more as otherwise he will always be a 'novelty' to the pups. He seems fairly tolerant but definitely doesn't want to play!
