Predator Pee 100% Fox Urine - Territorial Marking Scent - Creates Illusion that Fox is Nearby - 64 oz

Product Information

Foxes were obtained during winter (July and August) from three farming (grazing and agriculture) regions in Victoria: the Anderson Peninsula, Skipton, and Koo Wee Rup. Proprietary repellent substances used against cats and wild animals need frequent applications to maintain their effect and in some cases appear to be ignored. Another chemical theme was the presence in fox urine of many isoprenoids and related compounds that are well-known as plant chemicals.

In their exposure studies on six cats, which ran over two years, most cats responded to compounds that are structurally similar to nepetalactone such as iridomyrmecin. But despite being dubbed ‘kitty crack’, felines on nepetalactone don’t experience any withdrawal symptoms or other negative side effects. Loss of the sulfur moiety (-SH, -SCH3, -CH 2SCH 3 radicals, and related whole molecules) produced ions that distinguished thiols from methyl sulfides, and the 1- and 2-thio-substituted phenylethane isomers from each other.It was present in all four stir bar fox urine analyses, and has been found in urine of humans and captive animals but not in wildlife, presumably due to their lack of exposure. You can change your choices at any time by visiting Cookie preferences, as described in the Cookie notice. Acetophenone has been found in all previous fox urine studies but only sometimes found in the urine of other species, suggesting that its production is variable.

Animals learn to associate particular odours with characteristics of the emitting animal, for example detecting dietary-related compounds [ 66] or microbial products in a conspecific [ 67] or identifying predator or prey species [ 68].Thus, their expression as odourant molecules may act as a reliable olfactory signal of good nutrition.

Their ecological impact is profound in Australia, where they have spread throughout the continent since their introduction in the 19 th century [ 16].Such new methods may lead to longer-term and more effective control of fox numbers, bringing huge benefits to agriculture and biodiversity in Australia. This was calculated from the ratio of their peak areas to that of acetophenone, whose concentration (μg/ml) was determined from the ratio of its peak area to that of the internal standard, d 8-acetophenone. In further evidence of their chemical signalling, foxes exhibit marking behaviour with urine [ 31– 33] and faeces [ 34], and have an aromatic supracaudal tail gland [ 35] whose scent chemicals have recently been described [ 36]. The silver vine fruit galls (deformed fruits) are induced by the female gall midge Pseudasphondylia matatabi, who lays her eggs in the A.
