I have two dogs and two cats. One of my cats sometimes does "dog-like" things. I didn't choose him because of this, in fact he was too young for me to even know this about him. Maybe he picked it up from the dogs. But I still love him just the same. Both of my cats fetch toys. I'm beginning to realize this is not a dog thing afterall.
I don't read into that too much when people say it. It's not a big deal to me either way.
