I am wondering if the category of small categories $\mathbf{Cat}$  is known to (not)  have the Cantor–Schröder–Bernstein property? That is, for any two categories $\mathcal{C}$ and $\mathcal{D}$, does the statement that there exist embedding functors (monomorphisms in $\mathbf{Cat}$) $\mathcal{F}: \mathcal{C} \rightarrow \mathcal{D}$ and $\mathcal{G}: \mathcal{D} \rightarrow \mathcal{C}$ imply that $\mathcal{C} \cong \mathcal{D}$?

If not, what can we say about the validity of the following  weaker statement?

For any two categories $\mathcal{C}$ and $\mathcal{D}$, the statement that there exist embedding functors $\mathcal{F}_1: \mathcal{C} \rightarrow \mathcal{D}$ and $\mathcal{F}_2: \mathcal{D} \rightarrow \mathcal{C}$ implies that there exists bimorphisms (epic embedding functors) in $\mathbf{Cat}$ $\mathcal{G}_1: \mathcal{C} \rightarrow \mathcal{D}$ and $\mathcal{G}_2: \mathcal{D} \rightarrow \mathcal{C}$.

Thank you in advance for your help
