Yes, still remember it vividly.
Shadow fox seen by myself and my friend whilst in the car. She was driving, The fox was in the middle of the road chasing its tail.
We both saw it at the same time, looked at each other, then back at the road, my friend slowed the car down to about 10mph as we approached and then when we got about a car length away from it the fox just sort of disolved and both of us at the same time said wtf?
That was the first time either of us spoke. I then asked her what she saw and we agreed that it was a fox and was chasing its tail clockwise.
It was a cool experience.

I have seen a shadow cat. I was outside, and out of the corner of my eye I saw this big black cat, big as a bobcat, playing and pawing around at something on the ground. I froze and panicked at such a large cat, and then looked again. It was my neighbor's side of the fence, and there were 3 chickens pecking at the ground there, but no cat. I couldn't see the shadow straight on, but I figure the shadow cat was pawing around, and above, at the chickens. Coincidentally there was an actual normal domestic cat a dozen yards away, looking at the chickens. Hmm.

I've seen spirit lion-beasts. You know those she-bears that the one saint sent at the kids who called him a bald head? Similar idea. I saw a lion-beast like that at the command of an occult group of people. Not pleasant. Apparently the leader would use that lion to keep his weakling group of people from runinng away from him. Still a problem.

Yes, Ive seen shadow animals my whole life. I just ignore them for the most part. I do have a real life kitty that sometimes in the middle of the night, wakes me up, running up and down the stairs having a grand old time playing with one.

Also, last month, I was awake about 2 am, couldn't sleep, and watched for about 10 mins, 2 shadow what I would call squirrels running in rings around the trunk of a large tree off my front deck. About 20 feet off the ground, playing just like regular squirrels chasing each other.

I don't know too much about shadow animals, but the other night I thought I saw a creepy gray alien head moving across the face of my closet.
