Cat Scratch Fever carves a precise path across a steep slab wall that demands focus and finesse amid the soaring cliffs of Northern Mexico's Nuevo Leon region. This 140-foot single-pitch ascent rewards climbers with intense movement on thin holds, skirting just left of a striking black streak that punctuates the limestone. As each finger finds its place, the rock challenges with a blend of technical footwork and quiet power, inviting climbers to test their balance on this sharp vertical face. The wall stretches above you with a clean line protected by ten fixed bolts, offering a secure rhythm as you advance. Descending involves a straightforward rappel, dropping just right of the black streak—an easy-to-spot anchor that eases your exit from this focused sport route.

Located within the rugged terrain of Culo De Gato, in the Las Ventanas de Mina area, Cat Scratch Fever epitomizes the growing climbing scene of Northern Mexico, where limestone formations command respect and offer thrilling, data-driven challenges. The approach to the wall is manageable, with trails cutting through dry, sparse vegetation characteristic of the region’s semi-arid climate, making it essential to arrive early to beat the midday sun and carry ample hydration.

This climb’s 5.11a grade marks it as a step into demanding technical climbing for adventurers comfortable on sport routes but hungry for thin holds and slab precision. Climbers will appreciate the consistent bolt spacing that makes gear placements straightforward, allowing focus on body positioning. The route’s steep angle gives a refreshing break from overhung pitches and places a premium on smooth, controlled movement.

Beyond the technical elements, the surrounding landscape offers wide-open views framed by craggy ridges that pull the eye toward the horizon, where the desert meets the sky. The rock’s texture is clean limestone, occasionally textured enough to provide friction for smearing, encouraging steady footwork.

Plan your visit during cooler months to avoid the harsh heat typical of the region’s summers. Footwear with a snug fit and sticky rubber will make thin smears more manageable, and a helmet is always advised as loose rock, while uncommon, can occur off the approaches. Whether you come alone or with a group, this route introduces an excellent learning ground for steep slab climbing, making every move feel intentional and every clip a commitment. The climb offers an immersive connection to the arid landscape of Northern Mexico, balancing pure climbing enjoyment with practical challenges that sharpen skill and focus.
