#### Abstract

Let $\Omega \subset \mathbb{R}^N$ be an arbitrary bounded open set. We consider a degenerate parabolic equation associated to the fractional $p$-Laplace operator ${(- \Delta)}^s_p (p \geq 2 , s \in (0, 1))$ with the Dirichlet boundary condition and a monotone perturbation growing like ${\lvert \tau \rvert}^{q-2} \tau , q \gt p$ and with bad sign at infinity as ${\lvert \tau \rvert} \to \infty$. We show the existence of locally-defined strong solutions to the problem with any initial condition $u_0 \in L^r (\Omega)$ where $r \geq 2$ satisfies $r \gt N(q-p) / sp$. Then, we prove that finite time blow-up is possible for these problems in the range of parameters provided for $r, p, q$ and the initial datum $u_0$.
