I'm pretty sure the servals in Rabat aren't actually North African servals. North African serval is extremely rare in the wild throughout its range (was only rediscovered in Morocco in 2014) so would be unlikely for them to source from the wild. Moreover, Rabat is known to import a lot of animals from the Middle Eastern and subsaharan Africa collections.
Ahh sorry! I used a combination of Zootierliste and Joel Sartore's IDs to help with mine. I definitely defer to some more in the know like you @Mehdi . I've changed the ID to not include subspecies.
