Rats are various medium-sized, long-tailed rodents of the superfamily Muroidea. "True rats" are members of the genus Rattus, the most important of which to humans are the black rat, Rattus rattus, and the brown rat, Rattus norvegicus. Many members of other rodent genera and families are also referred to as rats, and share many characteristics with true rats.
Rats are typically distinguished from mice by their size. Generally, when someone discovers a large muroid rodent, its common name includes the term rat, while if it is smaller, the name includes the term mouse. The muroid family is broad and complex, and the common terms rat and mouse are not taxonomically specific. Scientifically, the terms are not confined to members of the Rattus and Mus genera, for example, the pack rat and cotton mouse.
The best-known rat species are the black rat (Rattus rattus) and the brown rat (Rattus norvegicus). The group is generally known as the Old World rats or true rats, and originated in Asia. Rats are bigger than most Old World mice, which are their relatives, but seldom weigh over 500 grams (1.1 lb) in the wild.

Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media.
Video systems vary greatly in the resolution of the display, how they are refreshed, and the rate of refreshed, and 3D video systems exist. They can also be carried on a variety of media, including radio broadcast, tapes, DVDs, computer files etc.
Video technology was first developed for Mechanical television systems, which were quickly replaced by cathode ray tube (CRT) television systems, but several new technologies for video display devices have since been invented. Charles Ginsburg led an Ampex research team developing one of the first practical video tape recorder (VTR). In 1951 the first video tape recorder captured live images from television cameras by converting the camera's electrical impulses and saving the information onto magnetic video tape.
Video recorders were sold for $50,000 in 1956, and videotapes cost $300 per one-hour reel. However, prices gradually dropped over the years; in 1971, Sony began selling videocassette recorder (VCR) decks and tapes to the public.

A rat's ribs are hinged at the spine, enabling it to easily squeeze through the tightest spaces—like the pipes draining your toilet. And rats are great swimmers too; they can hold their breath for up to three minutes.

"Awesome, Amazing Rat Tricks" Part 2! Four of my five talented rats return performing their latest incredible tricks: Famous (Pink-Eyed Himalayan Top-Eared), Suki (Brown Agouti Berkshire Dumbo), Shadow (Black Mismarked Irish Top-Eared), and Raven (Black VariBerk Dumbo). All behaviours are taught with positive reinforcement and clicker training. As you may notice, most of the tricks in this video are performed by Famous since the majority of the behaviours stem from retrieving, which is Famous' forte. She is the most advanced retriever in my mischief, although Suki is following closely in her pawprints. I hope you all enjoy! - NanaBorderCollie :) My rats are available for print ads, commercials, film, and other media work. If you are interested in using one or more of them for your p...
Watch Part 2: https://www.youtube.com/watch?v=0jo_EG7XqZQ A short video showcasing a handful of incredible rat tricks performed by my five talented rats: Suki (Brown Agouti Berkshire Dumbo Rat) Famous (Pink-Eyed Himalayan Top-Eared Rat) Raven (Black Variegated Berkshire Dumbo Rat) Shadow (Black Mismarked Irish Top-Eared Rat) Paris (Russian Blue Berkshire Dumbo Rat) All tricks are taught with positive reinforcement and clicker training. Most of the tricks in this video are performed by Suki, Famous, Raven, and Shadow, since Paris had undergone surgery during the time this video was filmed. You can read about her surgery on my blog: http://nanabordercollie.blogspot.com/2013/08/prayers-for-paris.html I have included footage of a few of her tricks that were filmed prior to her surgery, h...
When the rats run riot and the screen door slams,
When the trees grow quiet, nothing but cats and cans.
When the breeze says 'try it', but you can hardly see.
When your love has died, and you rat on me.
I see your eyes in the half-light,
I see the number on your wall.
Endless strange things I see at night,
You don't see anything at all.
Shine a light into your soul, city streets so freezing cold.
City shadows mark the route when they let the rats out.
Rats.
You call it love, all right.
That was the catch!
A cold suicide.
Let me place you in my past with other precious toys.
But if you're ever feeling low down in the fractured sunshine,
I'll help you feel the noise.
Shine down, you can go on home.
Shine down, go.
Rats.
You're working overtime!
You are the moon beyond your mind.
When the rats run riot and the screen door slams,
When the world goes quiet, you won't know where I am.
You could be my open road, you could be the reason why.
You could ease my heavy load, but I want to freeze you out now.
You can let it shine.
Keep that in mind.
When they let out a rat next time,
You could move a little closer,
Until you're leaning all up around my shoulder.
