cat : : a carnivorous mammal (Felis catus) long domesticated as a pet and for catching rats and mice — Webster
Cat (Felis catus, or Felis silvestris catus, literally “woodland cat”), often referred to as the domestic cat to distinguish from other felids and felines, is a small, typically furry, carnivorous mammal. It is often called house cat when kept as indoor pet or feral/feral domestic cat when wild. It is often valued by humans for companionship and for its ability to hunt vermin. There are more than seventy cat breeds recognized by various cat registries.
Cats are similar in anatomy to the other felids, with a strong flexible body, quick reflexes, sharp teeth and retractable claws adapted to killing small prey. Cat senses fit a crepuscular and predatory ecological niche. Cats can hear sounds too faint or too high in frequency for human ears, such as those made by mice and other small animals. They can see in near darkness. Like most other mammals, cats have poorer color vision and a better sense of smell than humans. Cats, despite being solitary hunters, are a social species, and cat communication includes the use of a variety of vocalizations (mewing, purring, trilling, hissing, growling and grunting) as well as cat pheromones and types of cat-specific body language. — Wikipedia

- Milk prebiotics are the cat's meowon March 9, 2021 at 8:38 pm
If you haven't been the parent or caregiver of an infant in recent years, you'd be forgiven for missing the human milk oligosaccharide trend in infant formulas. These complex carbohydrate supplements mimic human breast milk and act like prebiotics, boosting beneficial microbes in babies' guts. Milk oligosaccharides aren't just for humans; all mammals make them. New research suggests milk oligosaccharides may be beneficial for cats and dogs when added to pet diets.

The carbon-oxygen (C-O) bond in alkyl ethers can be cleaved using mild methods to simplify chemical syntheses by elaborating robust, readily available precursors. In a new report now on Science, Hairong Lyu and a research team in chemistry at the University of Chicago and the University of Pittsburgh, U.S. detailed how dibromoboranes reacted with alkyl ethers in the presence of a nickel (Ni) catalyst and zinc reductant to insert boron into the C-O bond. The subsequent reactivity affected the […]
