Veterinarians have found a solution to the challenge of providing effective pain relief to some of their most difficult patients: big cats.

Immunology researchers have found that bacteria present in the human gut help initiate the body’s defense mechanisms against Toxoplasma gondii, the parasite responsible for toxoplasmosis.

In 2002, leopards in were legally — but unsustainably — hunted by trophy hunters, and illegally hunted by farmers because of the threat they pose to livestock. In order to reduce leopard killings, scientists have worked with local policy makers to create sustainable conservation solutions. In 2006, recommendations were successfully implemented and by 2008 data showed that the plans were working.

Anyone who has ever had cats knows how difficult it can be to get them to do anything they don’t already want to do. But it seems that the house cats themselves have had distinctly less trouble getting humans to do their bidding, according to a new report.

Scientists are describing discovery and successful tests of the first once-a-month pill for controlling both fleas and ticks in domestic dogs and cats. 

Oscar the bobcat is healing by leaps and bounds after a team of surgeons repaired injuries he sustained after being hit by a car.

A marker in the blood of both cats and humans that was identified in a recent study might signal both species’ susceptibility for a painful bladder disorder called interstitial cystitis, a condition that is often difficult to diagnose.

Researchers have discovered a group of closely related living species that independently repeated the different step-like changes that occurred in the major diversification of their kind during the Cretaceous Period, roughly 100 to 90 million years ago. But remarkably, this group of species arose some 80 million years later.

Sport hunters are depleting lion and cougar populations as managers respond to demands to control predators that threaten livestock and humans, according to a new study.

In the Japanese art of paper folding, a series of folds can make the same sheet of paper into a ballerina or baby elephant. But try unfolding the baby elephant and making it into a ballerina. It’s like trying to make a neuron from a kidney cell. Epigenetics, it turns out, isn’t much different from this old Japanese art: Each fold, or epigenetic crease, both limits and permits further potential folds in a way that mirrors how epigenetic changes seal a cell’s fate.
