Cheetahs are better as pets than the other big cats - Lions, Tigers or Leopard. A Lion or Tiger, even if hand-reared, is still a killer that can turn on you. Cheetahs, on the other

hand, do not generally attack humans, and adapt better to human contact.

However, there are many obstacles to owning a cheetah as a pet.

Depending on where you live, you might need expensive permits, or a lengthy application process before you are allowed to keep a cheetah. In some places you simply will not be allowed to legally keep a cheetah.

You will also need the facilities to keep a cheetah. You will need a fair amount of space, you'll need to build a secure enclosure to keep the cheetah in. You will need to spend time with it regularly. You will need to buy a lot of meat to keep the cat fed.

If the cat does escape, it's likely to cause alarm or panic among your neighbours, so you will have to be prepared for that.

Cheetahs can live for 20 years in captivity, so you have to be prepared for that.

Ultimately, although the cheetah is the most tameable of all the big cats, it is not a domesticated animal, and even if reared from birth by humans, it is not going to be as tame as a dog or domestic cat. You will still need to behave carefully around it, or it could maul you.

           

Though wolves are trainable, they lack the same degree of tractability seen in dogs. They are generally not as responsive as dogs are to coercive techniques involving fear, aversive stimuli and force. Generally, far more work is required to obtain the same degree of reliability seen in most dogs. Even then, once a certain behavior has been repeated several times, wolves may get bored and ignore subsequent commands. Wolves are most responsive toward positive conditioning and rewards, though simple praise is not sufficient as in most dogs. Unlike dogs, wolves tend to respond more to hand signals than voice.Although they are more difficult to control than dogs, they can be easier to teach if the motivation exists.

Captive wolves have also been shown to be largely unsuitable for working as dogs do. German wolf biologist Erik Zimen once attempted to form a dog sled team composed entirely of pure wolves. The attempt proved to be a complete failure, as the wolves were far more prone to fighting than sled dog and ignored most commands. North American wolves and wolf hybrids were used as experiment  attack dog by the South African Defense force  in Apartheid South Africa in an attempt to breed animals capable of illegal  tracking . However, the experiment proved a failure and was discontinued due to the wolves' inability to follow even basic commands. However, their sense of smell apparently rivals that of most established scenthounds. Tests undertaken in the Perm Institute of Interior Forces in Russia demonstrated that high content hybrids took 15–20 seconds to track down a target in training sessions, whereas ordinary police dogs took 3–4 minutes. Their success has led to plans to use them as police dogs for the Russian police.
