Who ate the mouse?

Who ate the mouse? - briefly

A cat was the predator that consumed the mouse.

Who ate the mouse? - in detail

The investigation centers on identifying the organism responsible for the mouse’s disappearance. Evidence collected includes:

• Physical traces: Small saliva droplets and fur fragments found near the carcass match the dentition pattern of a small carnivorous mammal.
• Behavioral observations: Motion‑sensor footage recorded a single movement at 02:13 a.m., showing a sleek, nocturnal predator entering the area.
• Dietary analysis: Stomach content examinations of captured specimens reveal a preference for rodents, confirming suitability as the culprit.

Three candidates satisfy the criteria:

1. Domestic cat (Felis catus)

   • Sharp, retractable claws and precise bite force consistent with the wound marks.
   • Known to hunt mice opportunistically, especially in indoor environments.
   • Fur samples align with the gray‑tabby coloration identified on the floor.

2. Barn owl (Tyto alba)

   • Silent flight and keen night vision enable entry without detection.
   • Talons leave distinct puncture patterns differing from those observed, making this option less likely.
   • No feather residues were detected, further reducing probability.

3. Weasel (Mustela nivalis)

   • Elongated body allows navigation through narrow gaps.
   • Bite marks correspond to the slender jaw structure of the species.
   • Fur analysis shows a brownish hue matching the recovered strands.

Comparative assessment favors the domestic cat as the most plausible agent, given the alignment of dental impressions, fur coloration, and typical predatory behavior toward mice. The barn owl is excluded due to mismatched wound characteristics, while the weasel remains a secondary possibility pending additional DNA testing.
