AboutJonathan Wright Expertise I can answer questions about wild mammals, as well as other wild animals. I can also answer questions on extinct animals and zoos.
PLEASE DON'T SEND ME ANY QUESTIONS ABOUT PETS. IF YOU ARE REALLY WORRIED, YOU SHOULD CONTACT A VETERINARIAN. PLEASE DO NOT ASSUME THAT UNPAID PEOPLE ON ALLEXPERTS ARE AVAILABLE 24 HOURS A DAY AND WILL PROVIDE YOU WITH ADVICE THE MOMENT YOUR ANIMAL GETS ILL. Find out how to look after a pet before you get it. It is unfair to keep an animal in inappropriate conditions and give it the wrong food. If you can't keep an animal in good conditions, please don't bring it into your home. I'm not a vet and I don't have any expertise in animal medicine and care. I don't agree with people taking animals out of the wild and then expecting other people to give free advice on how to look after them. It is cruel to take animals away from their parents, who are able to look after the babies and may look for them, while putting their other babies at risk. You may need a licence to look after some animals. You may be breaking the law by keeping wild animals; please check with a local wildlife organisation.
IF YOU FIND AN INJURED ANIMAL, PLEASE CONTACT A WILDLIFE VETERINARIAN OR CHARITY AND LET TRAINED STAFF LOOK AFTER THE ANIMAL. DO NOT TRY TO LOOK AFTER AN INJURED ANIMAL IF YOU DO NOT KNOW WHAT YOU ARE DOING.
Please do not remove eggs from nests. The mother birds will know the right temperature for the eggs and will not sit on them if the temperature is warm enough for them to develop naturally. It is illegal to remove eggs of some species and, unless you have an incubator or a broody hen, the egg may not develop. If you are allowed to touch the eggs, you can candle them (check details on websites) to see if the eggs are fertile. If the eggs are not fertile, they will not hatch.
I do not agree with fights between different animals. Please do not ask me questions about them.

Question I have been told that the big cats can't purr. That the largest cat that can still purr is the Mountain Lion.
Can big cats still purr? If not what is the largest cat that can purr
Answer Dear Richard
Thanks for your question. I have looked up various publications and websites and the information seems to be contradictory, even within the same website.
http://www.lairweb.org.nz/tiger/big.html states that ‘big cats' differ from ‘small cats' because pf the hyoid bone, which connects the tongue to the roof of the mouth. The hyoid bone has an elastic segment in big cats, but is hard all over in small cats. The elastic segment allows big cats to roar, but prevents them from purring in the same manner small cats can. Small cats can purr when they inhale and exhale, but big cats can only produce a 'purring' type of noise, when they exhale. To confuse the matter, http://www.azdrybones.com/felids.htm implies that big cats can purr both while inhaling and exhaling; the other cats purr on exhaling only. I think that the site got its facts the wrong way round!
The answer to your question depends on whether you consider this noise to be a true purr or not. If you do, the largest purring cat is a big cat (see below). If like http://www.tigerfdn.com/Tigerworld/trivia2.htm, http://science.howstuffworks.com/question394.htm and http://madsci.wustl.edu/posts/archives/may96/828639116.Zo.r.html, you think roaring cats cannot purr and that a true purr can only be produced when the cat inhales as well as when it exhales, the largest purring cat probably is a mountain lion.
As there is so much disagreement whether or not big cats purr, it is difficult to give a definitive answer to your question. Looking at the evidence, it seems that tigers can produce a purring sound and, if this is defined as a purr, the tiger is the largest purring cat. If the tiger cannot produce a purring sound, the largest purring cat is the lion. If a purr is defined as a sound, which can be produced by inhaling as well as exhaling, the largest purring cat is a mountain lion.
Personally, I think that the bulk of the evidence indicates that the tiger can purr and is therefore the largest purring cat.
