Cat Brought a Mouse into the House: What to Do
When a cat drags a mouse into the home, the presence of natural predators can affect both the cat’s hunting instinct and the likelihood of future captures. Understanding which animals typically prey on rodents helps owners anticipate behavioral cues and choose appropriate interventions.. Date latest changes:
Protecting Foam from Being Gnawed by Mice
Mice gnaw foam because their instinct to explore and test objects with their incisors is hard‑wired. The behavior serves two evolutionary purposes: assessing material safety and maintaining dental health. Foam’s soft texture triggers these instincts, prompting rodents to bite and chew until the material is compromised.. Date latest changes:
What Fears Do Mice Have in the House?
Mice entering a residential interior display a set of instinctual defensive reactions that reduce exposure to potential hunters. The core mechanism, often described as «innate predatory avoidance», operates without prior learning and triggers rapid behavioral adjustments when sensory cues indicate danger.. Date latest changes:

Rat Mazes: Where to Purchase and How to Use
Rats thrive when their environment challenges their problem‑solving abilities. A well‑designed maze provides a series of decision points that compel the animal to navigate, remember routes, and adapt to new configurations. This continuous cognitive load prevents the development of stereotypic behaviors and supports neural plasticity.. Date latest changes:
Why Do Rats Have Hairless Tails?
Rats possess hairless tails that function as efficient thermal radiators. The absence of fur eliminates insulating layers, allowing direct contact between ambient air and the dense network of blood vessels beneath the skin. Blood flow through these vessels carries excess body heat to the tail surface, where convection and radiation dissipate it rapidly.. Date latest changes:
Rats leave clear evidence of their presence, and recognizing these indicators is essential for effective yard protection. Fresh droppings, dark and pellet‑shaped, appear near food sources, along fence lines, and under decks. Gnaw marks on wood, plastic, or metal reveal the size of the intruder;. Date latest changes:
Nepetalactone, a bicyclic monoterpenoid, is the primary volatile component of catnip (Nepeta cataria). The molecule exists in two stereoisomeric forms, trans‑ and cis‑nepetalactone, each contributing differently to olfactory perception. In felines, nepetalactone binds to olfactory receptors in the nasal epithelium, triggering a cascade that activates the vomeronasal organ and induces characteristic hyper‑reactivity..
