Welcome!! Definitely keep an eye on the kitties and Winston....we had an older cat when we got Jake and she got him right across the eye one night requiring a trip to the ER. Thankfully she did not puncture the cornea, just scratched it. Lots of people on here have cats and Cavaliers and have some really wonderful pictures of them together. It'll just take time.
I just adore that last picture of his little body with his hood up around his head!! What a cutie!!
Loving mom to Jake, Shelby and Micah
