I could be totally wrong on this but I recall on live servers as long as you didn't erase the entire pet name and used the arrow key or mouse pointer to erase partial names you could keep spacing in a pets name. e.I. "an albino wyrm" --> "The Big Wyrm" You were allowed to use spaces already provided in the name but couldn't backspace them or add new spaces. Was this intended or was it changed sometime during live and I just never noticed?
Zookeeper animals look noticeably different than the normal ones but I guess for someone not as educated on them all could get tricked easily. Maybe another fix is when lored they give the original name.
"Psst..... Hey kid..... you looking for some zookeeper animals?" *opens up trenchcoat* "I've got "a silverbak gorila" and "an Albyno Wirm"and "a frost baer".... super rare, very high quality. Guaranteed to be compatible with all leading zookeeper scroll brands."
Another thing we can do that is already on a few Zoo animals...just make all their names red...solved.
