Both those animals are Lemuridae, which are controlled under the DWA. The only exception within the family Lemuridae are Hapalemur (bamboo) lemurs
These lemurs have not been removed from the DWA yet, though a recent DEFRA proposal has suggested they be removed when the DWA is overhauled.
They have also recommended tamarins, owl monkeys, squirrel monkeys, wooly lemurs, porcupines, capybara, some
felis species, racoons, coatis, kinkajous, olingos, coatimundi, the biturong, hyraxes, sand snakes, mangrove snakes and the brazilian wolf spider are removed.
Whether any or all of these species will be removed remains to be seen.
