Tamed Animals won't teleport in snow.

So i am on my singleplayer world and i come across a snow biome with a village and i wanted to tame 2 cats which i did, so i loot the village and its time for me to head back to my home base, and i notice that my cats only teleport on on grass blocks. not snow blocks, here let me show you. and wolfs won't teleport either and they also won't teleport on frosted ice.
