It is an old idea with a grain of truth: get a cat and your rodent problem is solved. In Tucson, the reality is more nuanced — a cat helps with some rodents and does almost nothing about others, and it is never a substitute for sealing the house.
Cats and mice: some help
A motivated cat is a genuine deterrent to house mice. Mice are small, ground-dwelling, and within a cat's hunting ability, and the presence of a predator — the scent, the movement — can make a space less attractive to them. If your problem is the occasional garage mouse, a cat is a modest, real help.
Cats and rats: not so much
Rats are a different story. A pack rat can be nearly the size of the cat and is well able to defend itself; most house cats will not take on an adult rat, and many sensibly decline. Roof rats live in the one place a cat cannot follow — the attic and roofline, reached by tree canopy. A cat on the ground has no access to a rat living above the ceiling. So for Tucson's two most common rats, a cat is largely a spectator.
The bigger issue: cats do not seal the house
Even where a cat catches a rodent, it does nothing about the gap the rodent came through. The next one uses the same route. Rodent control is fundamentally about exclusion — closing the entry points — and a cat cannot screen a weep hole, seal a tile termination or replace a garage door seal. At best a cat trims a few individuals off a population that keeps being refilled through open gaps.
A safety note: cats and poison do not mix
If you keep a cat, that is one more strong reason never to use rodenticide. A cat that catches a poisoned rat can suffer secondary poisoning. It is one of several reasons we do not use interior poison — trapping and sealing protects pets while clearing the problem.
The best "natural predator" in Tucson is not the cat
If you want predation working for you, the animals that actually control desert rodents are owls, hawks, coyotes and bobcats. An owl box on a larger property genuinely helps, and protecting raptors — by never using poison — keeps that free control in place. A barn owl pair takes far more rodents than any house cat.
Quick answers
Will a cat get rid of my rats?
Unlikely. Cats help modestly with mice but rarely tackle adult pack rats and cannot reach roof rats in the attic. They also do not seal entry points, so the population keeps refilling.
Should I get a cat for rodent control?
Get a cat because you want a cat. As pest control it is a minor supplement to sealing the house, not a solution.
What works better than a cat?
Sealing the entry points plus trapping. That addresses why rodents are getting in, which a predator on the ground cannot.

Not sure what you are dealing with?
A free inspection identifies the species, every entry point and the scope of work — in writing, before anyone quotes you a number.
