Early in my career I was the vet for a local zoo. SOP was to take babies away from queens right after giving birth to prevent the queen from eating them in captivity out of stress.
I was charged with raising them. I had a jaguar cub, 2 lion cubs and 2 leopard cubs over a 14 month period. The Jaguar cub was my favorite. He was very gentle, lovable, cuddly and smart. Kept him until he was 6 months old and weighed 45 lbs. After he went back to the zoo I'd see him during my regular monthly rounds and he'd come right to me for petting even as an adult 5 years later. To me, Jaguars are the most beautiful of all the big cats.
The 2 lion cubs, both females, were more boisterous and rambunctious but still gentle and cuddly. They were also more than a little clumsy. I was able to keep them until they were 5+ months old, 50 lbs, in my house. On work days I could take the jaguar and the 2 lions to the animal hospital. That drew people from 20 miles away just to play with them in the waiting room. All 3 were gentle and playful. That was a blast.
One day a woman from Weston drove up in a Rolls Royce. She had heard about the lion cubs and wanted to buy one of them as a birthday present for her husband who was a big game hunter. He went on safari in Africa twice yearly. It was legal back then to own a big cat. The zoo agreed to sell her one for $500. She said she had the perfect place to keep the cub. Next morning, her husband, a dapper and handsome man, was waiting at the animal hospital before we opened. The cub was in a big dog crate. What happened? Turns out she put the cub in his trophy room with big leather sofas, animal skin rugs and stuffed animals he had killed. Separation anxiety times 10 for the cub. You can imagine the damage that lion cub did to his trophy room! The cubs were very happy to be united and she was very happy to be back home.
The leopard cubs were more primal and fiercely aggressive. There was no taming them no matter how much I tried. This was back in the mid '70s. There's a reason you
didn't see any leopards in circus acts. Cats from hell. Later I found out they are almost impossible to tame because they came out of womb feral - biting, scratching and clawing anything and everything. Very destructive. Plus they'd use the litter box then wallow in their excrement. Nasty, dirty creatures. 2 baths daily, minimum. In the picture you posted, the attendant is giving or has just given a bath and characteristically the cub has claws out wanting to scratch her. They went back to the zoo at 8 weeks with directions to keep the male and female apart so they couldn't breed any more. I had had enough of leopard cubs.
