Reoccuring theme of cats/white animals?

A few months ago I had I dream that I was going into my backyard, and when I opened the door, there were three white kittens sitting there. They all had blue eyes and kept trying to come into the house. Yesterday, I had a dream that I was in the yard with my dog and a white cat (I think it was a Persian) came up our driveway wearing a purple collar. My dog has never been near a cat, so I put myself between the two because I didn't want them to fight. The cat kept pawing at my jeans and tried to walk around me, to my dog, then by the door. I tried to scare the it by nudging it with my boots, but it kept moving or would rub against them.

Years ago I had a dream that a giant, albino bat was perched itself on my arm and I was petting it. When I stopped, it started attacking my left hand. It's not cat themed, but I figured I'd mention it since it also involves a white animal.

Normal I would brush this off as one of my nonsense dreams, but I've never had a reoccurring theme or anything before. Plus when the cat kept pawing me, it felt real; and I usually when I have vivid dreams they mean something.

(If it's of any importance, the cat with the collar was somewhat dirty, but the kittens in the first dream were snow white.
