This paper considers a general reaction-diffusion predator-prey model with indirect prey-taxis and predator-taxis {u t= d Δ u− χ∇⋅(u∇ m)+ c ϕ (u, v)− g (u), x∈ Ω, t> 0, v t= Δ v+ ξ∇⋅(v∇ w)+ f (v)− ϕ (u, v), x∈ Ω, t> 0, τ w t= Δ w+ β u− γ w, x∈ Ω, t> 0, τ m t= Δ m+ δ v− ρ m, x∈ Ω, t> 0, under homogeneous Neumann boundary condition in a smooth bounded domain Ω∈ R n. Here the parameters d, χ, ξ, c, β, γ, δ, ρ are positive, τ∈{0, 1}, and the functions f (v), g (u), ϕ (u, v) satisfy some general assumptions. For the system with τ= 1, under the assumption on the spatial dimension n≤ 3 and appropriate conditions on the parameters, the system possesses a classical solution which is global in time and bounded. Furthermore, for the system with τ= 0, under the assumption on the arbitrary spatial dimension n and appropriate conditions on the parameters, the globally bounded solution is also obtained.
