They say it could explain why dogs who spend more time indoors are more likely to get sick with diabetes, hypothyroidism and kidney disease.
Days ago, Elena brought up an interesting question in the We-chat group, saying that I have a dog and a cat. I love them both, but they just want to kill each other, what should I do? Back in my life, I have some friends keeping pets at home. Some people love dogs, and other people keep cats at home. But few people keep them both, even sometimes the owner keeps both dogs and cats at home, it seems that they could not get along well with each other. Considering they both are good companions of human being, why couldn’t they be good friends?
cats and dogs
I believe many of us must have heard this story. Once upon a time, a little mouse was chased by a cat. When the cat was about to catch his food, the mouse suddenly stopped and barked like a dog, and scared him away. This story told us the importance of learning a foreign language. Therefore, the first possible reason for the cats and dogs could not make friends is that they do not share the same language. According the scientific studies, both dogs and cats have their own secret language. While dogs have over 170 categories of barks, cats have few vocal sounds.
For dogs, they use different sounds to express different meaning. For examples, short and continuous barks, mean that “come on, and play games with me”. Short and loud barks indicate dangers. One bark indicate “open the door, I want to go out”. One long and low sound bark, means “I was hungry, please pass me a sausage”. If the dog howled liked a wolf, it means hey, I am husky. Compared with the rich sound of the dogs, researchers have figured out few sounds of the cat. For example, one mow means hey, I am coming. Two mows, hey I am going.
Because they do not share the same language system, there will be few chances for them to build up a good relationship. The worse thing is that, the only similar sound shared by them both has totally different meaning. It was observed by some zoologists that when a cat was happy and wanted to express some good feeling, it would make a low sound just like human being’s snoring. It meant to make friends with the dog. However, this sound was taken as a signal of threat for the dogs, refereeing as stupid dog, leave me alone. You see, although the cat expressed some good will, due to the language barrier, this good hope came to nothing.
In TMC, we understand that body language is also very important in communication. If I smile, you can tell that I am happy. If I shake my head, it means I don’t agree with you. The body language exists in the world of the dogs and cats too. But, the sad thing is that, just like vocal language, same body language can mean differently for the dogs and cats. If you keep a cat at home, you must know that if a cat is very happy, it will put up its tail. But for a dog, wagging the tail is the right way to show good will, and putting up tail means angry or hostile attitude. Again, the cats meant to make friends with the dogs, but the dogs get misunderstand. Gradually, they don’t like each other.
Apart from language barriers, another reason for the hostile status for dogs and cats can be traced to their different biological evolution. The ancient ancestors of both dogs and cats were the early carnivores, which referred to the animals that ate meat, in 65 million years ago. At that time, cats and dogs were not like the way they look nowadays. Their sizes were similar, their body was very long and their feet were very short. They both got 44 sharp and powerful teeth. Sadly, they loved the same food. They liked to haunt and catch small animals that only ate plants, so fights were inevitable. Sometimes dogs won, and other times cats won. This condition lasted for millions of years.
Later on, they experienced different degrees of evolution, and the dogs evolved to the current size in 15,000 years ago. Cats’ evolution took longer time and efforts. 9000 years ago, the cats finally became the appearance of what they are now. But the size of their bodies was not so big as before. From then on, cats often got beat in the battles against the dogs. A famous German archaeologist, Sherryman indicated that for many animals like cats and dogs, tigers and lions, they could not get along quite well, mainly because competitions always existed, when those animals were fighting for living materials in the long history of revolution. This competition lasts until today.
Then what if I love cats and dogs both, and I want to keep them both at home, what should I do? Well, to help them get along well with each other, you can choose to put them together when they were little, and prepare different food for them to prevent the potential competitions. Or you can take them to TMC, and make them learn the CC manual, I believe after finishing their CC, they can communicate with each other well and be good friend.

The claims are made in research contained in the latest edition of the Journal of Veterinary Behavior by Dr Franklin McMillan, a vet and former clinical professor of medicine at the Western University of Health Sciences College of Veterinary Medicine, in California。
They found that kitties mostly ingest parabens through cat food — with dry food containing more than wet — but pooches are also exposed to other sources of the po compound.
But experts say that in many cases obese dogs and cats are 'emotional eaters'。
He said 'emotional eating' in pets, could be triggered by feelings including boredom, anxiety and depression。
Today， dogs （and cats） “are fed diets that are relatively rich in fats and protein， not all of which may be completely digested， making their feces potentially attractive as a second hand food source，” Serpell told the Washington Post。
Dogs are ingesting the hormone-warping chemicals commonly found in makeup, creams and shampoos — and it could be making them sick, according to a new study.
That means, if they have gained weight, it could be because they have been through a traumatic or emotional event。
It‘s the moment every dog owner instantly regrets ever letting their dog kiss them on the mouth： Watching that very same beloved， seemingly well-trained and civilized pup eagerly devour a stinky， steaming pile of poop off the sidewalk。
New York State Department of Health researchers tested dogs’ and cats’ food and pee for the cheap preservatives known as “parabens” — which have been shown to have potentially harmful affects on health, according to their report.
New claims have also suggested that putting an overweight cat or dog on a diet could make them unhappy, because the owner is taking away their 'coping mechanism'。
Ugh， gross！ But why？ Why？！
Doting owners are often blamed when pets put on a few pounds。
That said， some great minds in the canine scientific community think there may be a bit more to it。 For instance， Professor James Serpell of the University of Pennsylvania and editor of the recent book The Domestic Dog： Its Evolution， Behavior and Interactions with People， told theWashington Post he finds the wolf theory “plausible，” but he‘s also intrigued by the “greedy eaters” survey findings。
He referenced a study of free-roaming wild dogs in developing countries that scavenge for food and， as a result， fill up on a sizable amount of human feces。 This seems to indicate that poop could be viewed， errr digested， as a second-hand food source。
he problem has been likened to that of Bridget Jones, the singleton who hides away from her troubled love life by eating, with vets believing some pets use food to cope with sadness, according to The Sunday Telegraph。
So， there you have it。 Poop-eating is probably a normal， evolutionary dog trait。

But research shows animals are less fussy, and will go on a comfort binge even if the only food on offer is their usual dog or cat food。
The study claims the obesity rate is as much as 25 per cent in cats, and 45 per cent in dogs。
They also consume more than they need simply to cope with boredom or stress, research has found。
Interestingly， the research suggested that the tendency towards coprophagia （the scientific term for poop-eating） was evident no matter a dog’s age， breed， diet， house-training status or compulsive behavior tendency。 This finding has unleashed a new theory： Modern day dogs have inherited both their aversion to pooping where they live as well as their likelihood to eat fresh poop from their ancient wolf ancestors。
You see， wayyyy back in those wild days， wolves may’ve eaten the fresh feces of sick， lame or old members who accidentally let a load loose as a way to clean up inside and around their den。 Since it takes about two days for parasites and other pathogens to develop， eating fresh poop is not usually dangerous， and in fact， eating poop that was festering in their living quarters was actually a helpful way to avoid intestinal parasites such as larvae and worms。
But the research has also suggested overeating could also be a sign of pleasurable emotional state, as well as a psychological state of turmoil。
However， a new study led by veterinarian Benjamin Hart， director of the Center for Animal Behavior at the University of California at Davis， has managed to link the off-putting behavior to “greedy eating” （dogs that quickly ravish their food bowls， according to owners） as well as an instinct connected to canines’ ancestral wolf pack days。
It；s a topic that has long perplexed animal researchers and veterinarians。 And if you Google the topic， you‘re likely to get more than a dozen different explanations ranging from canine anxiety to illness to simply boredom。
Comfort eating in humans tends to involve high calorie foods which the individual chooses, including ice cream, and chocolate。
The best thing to do， for now， is keep your dog on a short leash and make sure to pick up your own lawn。
As the Washington Post reports， Hart and his team surveyed over 3，000 dog owners。 Of these subjects， 16 percent ate other dogs’ feces “frequently” （their owners had witnessed a crappy chow down session at least six times）， and of those pups， 80 percent preferred fresh feces less than two days old。 Well， who doesn’t？
But， take heart： Hart and his team are working on a solution。 They’re currently looking at clinical trials of new methods and products that dissuade your pup from chomping down on their own or others’ droppings。
