Cat and horse nuzzle and snuggle each other
A classic cat/horse relationship of which there are many. Cats and horses go together despite the huge barrier of size-difference. This makes nuzzling and snuggling up tricky to say the least. Invariably the cat jumps onto a fence as we see here. At one stage the horse thinks about giving their feline friend a love bite! There is a size difference problem in the human-to-cat relationship as well, which forces the cat to make adjustments when expressing affection such as lifting themselves up onto their hind legs when greeting their owner.
