Cats and tamed wolves won't stop sitting.

Cats and tamed wolves won't stop sitting when I log into Minecraft while online.
My cat should have stood up when I right clicked on it.
I thought my cat should have stood up when I right clicked on it.

When I right clicked on my cat it wouldn't stand up.
I tried pushing it, feeding it raw fish, walking far away, and hitting it but nothing would make it stand up.
Steps to Reproduce:
1. Log into Minecraft while you are connected to the internet.
2. Get a cat (tamed ocelot)
3. Right click on it and see that it doesn't stand up

Note: The cat will stand up when I logged in while offline.
