This cat demonstrates the usual feline zero regard for personal space.
Looks like these are the same cats. Adorable!
The first video is from here and the second from here.
Thanks to the Eyebleach Subreddit for this short clip of an adorable cat being checked out by a very kind and gentle vet.
According to the reddit post, the cat’s name is Hosico and the clip was taken from a video of him on YouTube.
