ID of an entity doesn't register as a valid number (perhaps only ocelots)

I was creating sculptures based off of SethBling's sculptures video, and one of them was two ocelots kissing (by request of my brother). I tried to use /tp to turn the ocelot around by using "/tp @e[type=Ozelot] ~ ~ ~ ~180 ~". However, it returned with the error message: "[ocelot's entity id] is not a valid number". Please fix this or I will not be able to do my sculptures.

NOTE: When I did a sculpture of me (armor stand) shooting a creeper, the tp command worked fine.
