Outdoor walks provide pet rats with sensory stimulation that cannot be replicated indoors. Natural light, varied textures, and ambient sounds engage their whiskers, paws, and auditory system, promoting neural development and reducing monotony.. Date latest changes:
Predators that hunt rats in natural environments exert direct pressure on rodent numbers, limiting population spikes that could otherwise destabilize food webs. By removing excess individuals, these hunters maintain a balance that supports the diversity of other species sharing the same habitat.. Date latest changes:
Rats are omnivorous rodents that may encounter milk in laboratory settings or as accidental food sources. Their ability to process milk depends on the presence of the enzyme lactase, which hydrolyzes lactose into glucose and galactose. In most mammals, lactase activity declines sharply after weaning, rendering adult individuals lactose intolerant.. Date latest changes:
When a rat shows no movement, the most reliable conclusion is death. Absence of locomotion eliminates the possibility of normal activity and requires verification through additional observations.

Porphyrins are tetrapyrrole pigments synthesized in the lacrimal glands of rodents. In rats, these compounds are secreted in the tear fluid and appear as a reddish‑brown fluid that can be mistaken for nasal hemorrhage. The biosynthetic pathway begins with δ‑aminolevulinic acid, which undergoes condensation to form porphobilinogen, followed by successive enzymatic steps that generate uroporphyrinogen III and coproporphyrinogen III..
