**I was transporting my new cats trough the nether and all my cats walked into a lava fall.

What I expected to happen was...:
My cats avoiding the lava and passing it safely.

What actually happened was...:
My cats all walked into the lava and some actually teleported in the lava.

Steps to Reproduce:
1. Tame a cat
2. Take it to the nether
3. Walk near lava falls and watch your cats walking into the lava
