Black rat
The black rat—also known as ship rat, roof rat, or house rat—is a common long-tailed rodent of the stereotypical rat genus Rattus, in the subfamily Murinae. Black rats are generalist omnivores. They are serious pests to farmers because they eat a wide range of agricultural crops. They are black t…
What do Rattus rattus eat?
Rattus rattus generally feeds on fruit, grain, cereals, and other vegetation. It is an omnivore, however, and will feed on insects or other invertebrates if necessary. It consumes about 15 g/day of food and 15 mL/day of water. Because it consumes and destroys the food source during feeding, it can cause devastating damage to farms and livestock.

Do black rats eat arthropods?
Arthropods, particularly insects, are an important dietary component of most black rats, but they typically comprise a smaller component of the R. rattus diet relative to vegetative material [ 16 ]. The diet of black rats was 98% plant material, the seeds of Miconia robinsoniana being dominant, and only 2% arthropods.

Abstract
Introduced rodents are responsible for ecosystem changes in islands around the world. In the Galapagos archipelago, their effects on the native flora and fauna are adverse, including the extinction of endemic rodents in some islands and the reduction in the reproductive success of the Galapagos petrel ( Pterodroma phaeopygia) in its nesting zones.

Introduction
Introduced rodents on islands are associated with altered terrestrial communities and modified ecosystem properties [ 1, 2 ]. Rodents directly impact terrestrial communities by feeding on plants and animals [ 3, 4, 5] and are a significant threat to island bird populations [ 6 ].
Methods
This research was performed as part of a petrel population monitoring and control of introduced rodents’ species by the Galapagos National Park (GNP) under the research permit No PC: 36–13 approved and supported by this institution.
Results
The black rat (n = 43) and house mouse (n = 17) were collected at all four sites, whereas the Norwegian rat (n = 4) was only captured at La Comuna. The rats were dominant in captures (average capture percent (ACP) = 73.6%) compared to mice (ACP = 26.4%), which had a capture rate between 25% and 33% compared with the 69% to 77% recorded for rats.
Discussion
The presence of black rat and house mouse has been recorded in petrel nesting colonies on several islands [ 8, 27 ]. Nonetheless, this study is the first record of the Norwegian rat and the subspecies of black rat R. r. frugivorous at these sites on San Cristóbal Island.

What do black rats eat?
Their only source of food in these otherwise sterile forests is the pine seeds , which they obtain from the cones by a complex feeding technique. We studied the rats’ acquisition of this feeding behavior and its transmission from one generation to the next. Naïve adult black rats were unable to acquire the technique through trial and error or observation of experienced rats, but only gnawed at the cones randomly in an energy-wasteful manner. Pups, however, were able to learn the technique through observation. Flavor of the mother’s milk was eliminated as a possible cue. Cross-fostering pups born to “naïve mothers on experienced mothers and vice versa revealed that the pine cone stripping technique is socially rather than genetically transmitted. When we exposed naïve adult rats to pine cones from which the rows of scales at the base of the cone had been previously stripped, the majority of the naïve adult rats did learn to strip the cones, although the number was less than that of pups learning from their mothers. Of the two methods observed to be employed by the rats to obtain the seeds (stripping and shaving), stripping was the preferred method and shown to be more energy efficient. The young rats must acquire this feeding behavior while they are still in the vicinity of the mother as this is their only opportunity to learn the stripping technique from her; without this skill they could not survive in the pine forest habitat. The present study exemplifies the significance of the ontogeny of a specific feeding behavior in examining the energy budget and transference of knowledge from one generation to the next by means of cultural transmission. Learning the most efficient way to obtain food is essential and often critical for survival. It is possibly the most important factor involved in the widespread distribution of the species in a natural habitat.
How many rats learn to open pine cones?
Less than 6% of rats captured outside pine forests and given pinecones to eat learn to open them efficiently. However, more than 90% of rats born to mothers that could not remove the scales from pine cones efficiently but reared by foster mothers that stripped pinecones in the presence of their foster young, learned the efficient method of removing scales from cones.
Where did the rat lungworm originate?
The rat lungworm was first discovered from the pulmonary arteries of Rattus rattus and R. norvegicus in Guangzhou, China in 1933 ( Chen, 1933) and named as Pulmonema cantonensis ( Chen, 1935 ). The parasite was also reported as Haemostrongylus ratti in Taiwan in 1937 ( Matsumoto, 1937; Yokogawa, 1937 ).
Where do black rats live?
Black rats ( Rattus rattus) living in the pine forests of Israel and of Cyprus (places where no squirrels are present to compete for pine seeds), but not black rats living elsewhere, subsist on a diet of pine seeds that they secure by stripping the scales from pinecones and eating the seeds that the scales protect.
Do rats learn to strip pine cones?
When we exposed naïve adult rats to pine cones from which the rows of scales at the base of the cone had been previously stripped, the majority of the naïve adult rats did learn to strip the cones, although the number was less than that of pups learning from their mothers.

How much sugar do rats eat?
These animals not only have a broad palette for the food they eat; they also eat a lot of it. Rats will typically eat around about 5% of their body weight in food every day. For a rat of a typical size and age, this means a food intake of 10-30 grams per day. For some perspective, a teaspoon of sugar weighs about four grams.
How much food should a 200 pound man eat?
If a 200-pound man ate as much as a rat does, he would need to consume a whopping ten pounds of food every day . Because rats eat so much, their volume of feces is high, as well. This is in-line with the practice of coprophagy mentioned above.

Why is neutering rats important?
Spaying and neutering is very important (people often forget this with their dogs and cats, so why would they remember a little rat). Neutering males at a young age will greatly reduce scent marking, and the males will have soft fur from lack of buck grease production. Males can also get mammary tumors, so neutering will reduce that as well. Contrary to popular belief, neutered male rats (and other males of the dog and cat species) still get very large sized. Neutering early will also greatly reduce aggression tendencies, such as those brought on by puberty (can be violent).
Why do you spay a female rat?

She hasn't had any of the health problems normally associated with aging.

Can hairless rats get lint in their eyes?
They can get lint (IE carefresh bedding which is JUNK, do not use) stuck in the corners of their eyes, but hairless rats are more prone to this. If the material remains in the eye, it can cause ulcers, which can render the eye useless and it will need to be surgically removed. Ulcers are extremely painful, so if you see one of your rats squinting, some porphyrin around that eye, try flushing the eye with some lukewarm saline solution.
