Chaser is a Border Collie with the largest tested memory of any non-human animal. She can identify and retrieve 1,022 toys by name. Here's a video of Chaser demonstrating her learning new words by "inferential reasoning by exclusion", that is, inferring the name of a new object by excluding objects whose names she already knows. ...

“This goes against the lore that you should have the dog sleep elsewhere,” and not in the bedroom, said Dr. Lois E. Krahn, a psychiatrist and sleep medicine specialist at the Center for Sleep Medicine at the Mayo Clinic.
She studied 40 dogs (none were puppies) who slept in the bedroom with their owners. The humans were all generally good sleepers, with no known sleep disorders.
Over seven days of testing, the researchers found that with a dog in the bedroom, both the humans and the dogs slept reasonably well. Humans had a mean sleep efficiency, or the percentage of time spent asleep while in bed, of 81 percent, while dogs had a sleep efficiency of 85 percent. Levels over 80 percent are generally considered satisfactory. People slept slightly better when the dog was off the bed; dogs slept the same whether they were on the bed or in another location in the bedroom.
New research has found cats can discriminate their names from other words. Researchers performed a series of experiments with house cats and cats from a "cat cafe" in Japan to see how the pets responded to hearing their names, general nouns and the names of other cats they live with.
After studying a total of 78 cats, the authors found that cats in regular households could differentiate between their names and other names and nouns.
"These cats discriminated their own names from general nouns even when unfamiliar persons uttered them." the report reads. "These results indicate that cats are able to discriminate their own names from other words."
