Cat Bell
A cat bell is a bell attached to the Cat collar, collar of a cat to prevent the cat from harming local wildlife. The bell can warn potential prey of the cat's approach. Cats eventually learn to walk without ringing the bell and pet owners are therefore encouraged to regularly change the bell or attach two bells on the collar. Attaching a bell on a cat's collar has been shown to reduce the amount of captured birds by 30–40%. With one collar, birds were found to be hunted 2.7 times less than without the collar. However, some animal care organizations also claim that cat bells are irritating to cats due to their sensitive hearing, and may just confuse birds by interfering with their natural defense mechanisms. Some owners worry that as well as alerting prey, a bell could alert large predators to a cat’s presence, given most predators' acute hearing. However, the acute hearing of predators is good enough that it is unlikely to make a difference in practice.{{Cite web , title ...

Bell
A bell is a directly struck idiophone percussion instrument. Most bells have the shape of a hollow cup that when struck vibrates in a single strong strike tone, with its sides forming an efficient resonator. The strike may be made by an internal "clapper" or "uvula", an external hammer, or—in small bells—by a small loose sphere enclosed within the body of the bell (jingle bell). Bells are usually cast from bell metal (a type of bronze) for its resonant properties, but can also be made from other hard materials. This depends on the function. Some small bells such as ornamental bells or cowbells can be made from cast or pressed metal, glass or ceramic, but large bells such as a church, clock and tower bells are normally cast from bell metal. Bells intended to be heard over a wide area can range from a single bell hung in a turret or bell-gable, to a musical ensemble such as an English ring of bells, a carillon or a Russian zvon which are tuned to a common scale and ins ...

Cat Collar
A cat collar is a piece of material put around the neck of a cat. Cat collars are used for identification, fashion, protection (as from fleas), restraint, or to warn off prey, and may be worn by cats that are indoor-only as well as cats with outdoor access. Collar safety As of 2021, there is ongoing debate about whether standard or breakaway collars (collars that unclasp with the application) are safer, or if cat collars are safe at all. A 2010 study reported on in the New York Times showed that simple buckle collars are actually the safest for cats. Another study from 2013 showed that the dangers to a cat that is lost outside without a collar (or having lost its collar) were substantially greater than the danger of a cat hurting itself on its collar. However, vets and animal welfare organizations continue to primarily recommend breakaway collars, as they present the least risk of a cat injuring itself on a collar. Types of collars Typical cat collars may be secured on th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prey
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators. Predators may actively search for or pursue prey or wait for it, often concealed. When prey is detected, the predator assesses whether to attack it. This may involve ambush or pursuit predation, sometimes after stalking the prey. If the attack is successful, the predator kills the prey, removes any inedible parts like the shell or spines, and eats it. Predators are adapted and often highly specialized for hunting, with acute senses such as vision, hearing, or smell. Many predatory animals, both vertebrate and inv ...

Pet Owner
A pet, or companion animal, is an animal kept primarily for a person's company or entertainment rather than as a working animal, livestock, or a laboratory animal. Popular pets are often considered to have attractive appearances, Animal cognition, intelligence, and relatable personalities, but some pets may be taken in on an altruistic basis (such as a stray animal) and accepted by the owner regardless of these characteristics. Two of the most popular pets are dogs and cats. Other animals commonly kept include House rabbit, rabbits; ferrets; domestic pig, pigs; rodents such as gerbils, hamsters, chinchillas, rats, mice, and guinea pigs; birds such as parrots, passerines, and fowls; reptiles such as turtles, lizards, snakes, and iguanas; aquarium, aquatic pets such as fish, freshwater snails, and sea snail, saltwater snails; amphibians such as frogs and salamanders; and arthropod pets such as tarantulas and hermit crabs. Small pets may be grouped together as pocket pets, while t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It was officially renamed Sveriges Radio in 1957. Sveriges Radio was originally responsible for all broadcasting in Sweden, both radio and television, and hosted the 1975 Eurovision Song Contest.
