You could probably answer this question using this resource [1]. However, someone used it to show no associations between psychotic episodes (specifically) AFTER controlling for other factors (that are associated with cat ownership)[2]. Using the adjustments they made, I could wildly speculate that possibly dog owners will be less likely than cat owners to have mental illness, because dogs require a certain amount of wealth, living space, etc - and the lack of these things is associated both with cat ownership and mental illness, maybe, just not in rural areas...
