Felids and canids coexist along their ranges worldwide. Various interactions can occur between these carnivores, with multiple consequences such as demographic changes of competitors, or behavioural modifications in the use of the spatial, temporal or trophic niches. European wildcats (Felis silvestris silvestris) and red foxes (Vulpes vulpes) coexist across Europe using multi-use landscapes when hunting rodents. They commonly use open fields during the day in the Cantabrian Mountains (NW Spain). We collected 597 diurnal phenotypic wildcat observations between 2012 and 2019, during which we observed 14 encounters (2.34%) of wildcats and foxes. We compiled 11 more encounters from collaborators. Diurnal encounters between both species seem to be rare, which could result from the two species displaying active avoidance. During the encounters, foxes mainly showed offensive behaviours whereas wildcats showed a defensive intimidation strategy, probably in relation to their morphology. Both strategies were equally effective for maintaining the position in feeding grounds.

猫科动物和犬科动物在全世界范围内共存。这些食肉动物之间可能发生各种相互作用，产生多种后果，例如竞争对手的人口统计变化或使用空间，时间或营养位的行为改变。欧洲野猫（Felis silvestris silvestris）和赤狐（Vulpes vulpes）在狩猎啮齿动物时使用多种景观在欧洲共存。他们通常在白天在坎塔布连山脉（西班牙西北部）使用开阔的田野。在2012年至2019年之间，我们收集了597个昼夜表型野猫观测值，在此期间，我们观察到14次（2.34％）的野猫和狐狸相遇。我们还收集了来自合作者的11次相遇。两个物种之间的昼夜接触似乎很少，这可能是由于两个物种表现出积极回避的缘故。在相遇中，狐狸主要表现出攻击性行为，而野猫则表现出防御性恐吓策略，这可能与其形态有关。两种策略对于维持进食地的位置同样有效。
