We study the infinite-dimensional Lindblad generator $L_\epsilon=D[a^2-\alpha^2]+\epsilon D[a]$, describing a dissipative cat qubit subject to single-photon loss. For sufficiently large $\alpha$ and sufficiently small $\epsilon>0$, we identify a two-dimensional spectral subspace near zero and establish an upper bound on the slow decay rate that decreases exponentially with $\alpha^2$, uniformly in $\epsilon$. This proves exponential suppression of bit-flip errors.
