How a Rat Steals a Chicken Egg: Behavioral Details
Rats that regularly infiltrate poultry coops belong to a small group of globally distributed species. Their physical size, climbing dexterity, and omnivorous diet make them capable of extracting chicken eggs from nests and cages. The brown rat (Rattus norvegicus) dominates temperate regions and urban environments.. Date latest changes:
Rat Breathing Difficulty: Causes Without Wheezing
Observe the rat’s thoracic and abdominal movements continuously. Normal respiration appears as regular, rhythmic expansions of the chest and belly with a rate of 80–150 breaths per minute in adult rats. Deviations—irregular timing, shallow or exaggerated excursions, or prolonged pauses—signal potential respiratory distress even when wheezing is absent.. Date latest changes:
What Treats Can Be Given to Rats?
Rats require a balanced intake of macronutrients and micronutrients to maintain health and support growth. Protein supplies amino acids for tissue repair and enzyme production; sources include soy, fish, and lean meat. Fats provide essential fatty acids and energy;. Date latest changes:
Cottage cheese can be offered to rats, but its safety depends on several factors. The product provides protein, calcium, and modest fat, which can supplement a rodent’s diet. However, its lactose content may cause digestive upset in rats that lack sufficient lactase activity.. Date latest changes:
Why Do Rats Experience Nosebleeds
Porphyrins are pigments excreted by the Harderian gland of rodents and can appear as reddish droplets around the eyes, nose and whisker pads. When rats groom themselves, porphyrin‑laden secretions may be transferred to the nasal mucosa, creating a crimson film that resembles hemorrhage.. Date latest changes:
Nosebleeds in Pet Rats: Causes and Treatment
A nosebleed, medically termed epistaxis, denotes the escape of blood from the nasal passages. In small mammals such as pet rats, the event usually appears as fresh blood staining the nostrils, whiskers, or surrounding fur.
