This tendency in combination with their proximity to students has led squirrels to associate humans with food, [20] with some being documented boldly stealing food. [28] Student newspapers have documented squirrels eating trash, [29] with research on the matter finding that gray squirrels indeed consume anthropogenic food waste found on college ...
The biggest source of food for tree squirrels is tree nuts. Red squirrels store nuts in a single stash (a midden) that tends to dry out, so the seeds don't take root. Fox squirrels and gray squirrels bury nuts over a widespread area (scatterhoarding), and often forget them, resulting in new trees . [51] [52]
Due to the dearth of trees in their native Ireland for them to reside in, red squirrels are the only species being harmed by the invasion of grey squirrels. [77] The squirrel can, therefore, compete more effectively for a larger share of the available food, resulting in relatively lower survival and breeding rates among the red squirrel.
Squirrels, being primarily herbivores, eat a wide variety of plants, as well as nuts, seeds, conifer cones, fruits, fungi, and green vegetation. Some squirrels, however, also consume meat, especially when faced with hunger. [21] [32] Squirrels have been known to eat small birds, young snakes, and smaller rodents, as well as bird eggs and insects.

Commentators often embellish and parody descriptions of the squirrels responsible for interrupting electrical service with allusions to military action or concerns, for example: "Squirrels mobilize, plot acts of ...
The majority of cases are due to the animal's bite. It can also be transmitted through food or water contaminated with rat feces or urine. Other animals can be infected with this disease, including weasels, gerbils, and squirrels. Household pets such as dogs or cats exposed to these animals can also carry the disease and infect humans.
Animals like dogs, cats, squirrels, and other small animals are affected not only by second-hand smoke inhalation, but also nicotine poisoning. [ citation needed ] Domestic pets, especially dogs, usually fall ill when owners leave nicotine products like cigarette butts, chewing tobacco, or nicotine gum within reach of the animal.
UK squirrelpox virus is an entirely different virus to that which causes skin fibromas (tumours) in American grey squirrels. UK grey squirrels carry the virus but are unaffected by it whereas in red squirrels, the virus causes skin ulcers, lesions, and scabs. It can also cause swelling and discharge (from the lesions/scabs) near the eyes, mouth ...
