Better Pets - ONLY 1 COMMAND

Hello everyone! Welcome to my first command block creation,which is the "Better Pets" command.

What this command does,is it gives almost every animal a function. If,for example,you want night vision,you can tame a ocelot and then,when you are near the ocelot you will get night vision. You can also attach a lead to the ocelot for him to come to you so you have night vision everywhere.
