Helloo Beth and

to Purrs
I would tie the dogs up, and let kitty be free (not caged

) that way if Kitty requires some high ground (escapage)
there will be nothing stopping her ( remember and wear some protective clothing

)
its easier when the dogs are young, Here's Hamish sleeping in harmony with Casar

older dogs are a wee bit harder to learn, especially when their as daft as a brush

Misty and Prince playing, with cindy observing in the background
(because she was old and wise , and knew better

)

good luck with whatever you decide
