I think they arrived from Colchester and could've been from the 2021 or 2022 litters. The 2021 litter (Zuma and Zuri) was 1:1, and I believe the 2022 litter was 3:1, with the trio of males now at London. Do you know if this individual (and the other one) are/were male or female? This looks like it could be a female to me, so maybe they received 0:2 originally?
