They might prefer fruits, vegetables, grains and seeds, meat or nectar.
State of the art A Jurassic Park situation of dinosaurs once more roaming the Earth remains a fantasy. With current technology, DNA samples only remain useful for about 1 million years — so theoretically we could clone a Neanderthal, but not a Triceratops last seen 65 million years ago.
Woolly mammoth DNA is more accessible. We have flash-frozen mammoth samples and can implant the genetic material into elephantswhich are genetically similar.

The science has come a long way since Dolly the sheep was cloned insays University of Connecticut biotechnology professor Xiuchun Cindy Tian, who is working on reactivating nucleus-based DNA through cloning.

By one estimate a woolly mammoth-elephant hybrid is only a few years away. Inthe San Diego Zoo planned to display a cloned gaur Indian bison named Noah, although he died of an infection after two days. The zoo later housed Jahava, a banteng a type of wild cattle from South East Asiafor seven yearsuntil Jahava broke a leg and was euthanised.
So the main obstacles may be financial and political, rather than scientific, Tian says. For one thing, mortality rates for cloned animals are initially very high.
Still, similar questions might be raised about producing livestock in general. And the success rates are increasing. Inscientists used cloned embryos to get one successful Dolly. The only current productive use of animal cloning is for prize beef bulls, whose genetic stock is valuable to farmers.
Cloning wild or endangered animals would be even more expensive, as we have less information about them and fewer specimens to use as tests. But one area that might allow non-scientists to interact with clones is in tourism for wealthy individuals. Jaded travellers might pay through the nose to hunt cloned animals in South Africa, eat cloned animals in Japan, or spot clones of endangered animals while on safari in the US.

Controversially, the Namibian government auctions off several permits each year to hunt the endangered black rhinoarguing that the money is essential for conservation programmes and only non-breeding rhinos can be hunted.
Cloning could make both experiences accessible to more visitors. And of course zoos and safari parks around the world already display endangered animals. Many of them participate in biodiversity programmes aiming to keep endangered animals from going fully extinctor from becoming dangerously inbred as there are so few, for instance, black-footed ferrets.
So it could be argued that applying cloning technology for similar tourism purposes is, while expensive, not hugely different from an ethical standpoint. But in future conservation parks featuring cloned animals, she envisions the technology rather than the animals being the focus.
A de-extinction park, for instance, would be about celebrating human ingenuity as much as marvelling at the animals: The two researchers can also imagine people cloning endangered animals for food.

This sort of irresponsible de-extinction might occur for a variety of reasons, perhaps to provide a novelty attraction for a zoo or park. This sort of treatment of an animal would certainly seem to be wrong because of the exploitation of the species. Explain the reasoning behind your view, Zoos are morally wrong (animal rights standpoint not environmental) even if that means becoming extinct.
Extinction in the wild is not an excuse to continue keeping individuals in captivity. The survival of the species does not justify the loss of freedom for the individuals in captivity.
