This is the final Tom & Jerry cartoon with Mammy Two-Shoes, which turns out to be a tad funny with the maid's new mechanical cat blasting away Jerry at every turn. But, when it attempts to catch the mechanical mice Jerry lets loose in the large house, plenty of slapstick disaster happens - from breaking kitchenware to cutting a piano in half. Not too hilarious as earlier cartoons with Mammy Two-Shoes in it overall. More average.Grade C+

The 1950s saw the dawn of the space age, mankind spellbound by the advanced technological marvels of the foreseeable future. This T&J cartoon sees Mammy Two Shoes (in her final appearance) embracing the wonders of modern science by purchasing Mechano, an amazing mouse-catching robot cat, making poor Tom redundant in the process. At first the machine does its job brilliantly, but Jerry, keen to get back to the comfort of his mouse-hole, throws a few spanners (or wind-up mice) in the works.Push-Button Kitty has a great central idea, and Mechano is a cool creation, armed with saws, axes, dynamite and a gun, the metal moggy causing more mayhem than Tom ever did; but despite a fast pace and lots of chaos, this one simply doesn't deliver enough solid laughs to qualify it as one of the more entertaining of Tom and Jerry shorts.

In an unusual twist, Jerry winds up keeping Tom from being booted out of the comforts of home in this episode. The cat had gotten in trouble because he wasn't doing his job - getting rid of Jerry."It's progress, the Machine Age and stuff like that," explains Beulah (a.k.a. "Mammy Two Shoes"). You see, the mailman just brought Beulah a mechanical cat, something she sent away for since Tom doesn't seem to care about getting rid of Jerry. The gizmo is called "Mechano - The Cat Of Tomorrow." It is a little robot that promises to be "clean, efficient and dependable. On its first try, it grabs Jerry, sweeps him into a compartment and then deposits him outside. Bang! - just like that - the mouse is history and there is no need for Tom.Beulah laughs her nasty butt off as a dejected Tom leaves, telling him, "Maybe you can find an old-fashioned house, that needs an old-fashioned cat. Hee hee hee." How to get rid of the mechanical cat so things are back are normal comprises the bulk of the story with Jerry - more than Tom - doing the work......and the results pretty funny. This is an original story, something different from the norm and it was very entertaining.

Mammy Two Shoes, disgusted at the laziness of Tom, has previously placed an order for Mechano, a robot cat, which arrives one morning. After she demonstrates Mechano's effectiveness at ejecting Jerry from the household, a now-redundant Tom packs his things and leaves the house.Jerry, meanwhile, tries many ways to outfox the mechanical moggie...This is a fast-paced, very entertaining cartoon. It was also the last one to feature the dark-skinned, drawling Mammy Two Shoes. The race laws had somewhat changed the previous year, and the character was now no longer appropriate, so she was finally ejected from the series after just over a decade.
