Cat is about 13 and got dog as a puppy 3 years ago. Cat is a bit of a grump at times.
generally there’s a healthy respect from dog to cat. And if cat is sitting in doorway dog won’t go through. Not sure if ca5 does this on purpose but I think he does.
cat has taken to sleeping in The dogs bed upstairs in the day…dog sleeps in our room at night , cat downstairs, and if cat (v quietly ) scratches on door in morning for breakfast the dog goes mad barking.
it’s not an easy relationship….but they basically muddle along.
