The Mansion Cat is a 2001 Tom and Jerry cartoon that premiered on April 8th, 2001 on Boomerang.
The cartoon begins with a iris showing Jerry running, but as the iris disappers, it is shown that Jerry is going nowhere; Tom has captured his tail. However, when the owner calls his name, he lets Jerry's tail go, freeing Jerry back into his cage. The owner (voiced by Joseph Barbera) of Tom and a large house tells Tom he is going away for a while, the house is in perfect shape, and that he does not want Tom blaming "the mouse" for any destruction this time. Of course, this means Tom will spend most of the picture chasing Jerry around the house, causing extensive damage.
First, Tom throws the habit-rail out of the mansion, sits on the sofa, eats a lot of food stolen from the refrigerator, and watches TV (note: Muscle Beach Tom was shown on TV). Then, traditional chase and damage happen. Among the sequences: Jerry shoves Tom into a VCR, then shelves the resulting cassette-sized cat; Tom traps Jerry in a coffee maker; Jerry traps Tom in a refrigerator, and he comes out again in ice cubes; Jerry sucks Tom and half the living room into a vacuum cleaner; Tom chases Jerry through the yard and into the house on a riding lawn mower. At the end, he crashes the mower into his owner's returning car, who tells Tom he "makes a better hood ornament than a house cat".
- The short is dedicated in memory to William Hanna, who passed away on March 22nd, 2001, just a few days short of the short's debut.
- When Jerry sucks the curtain in the living room into a vacuum cleaner, Spike makes a cameo appearance.
- Despite the short being released in 2001, it is revealed to be made in 2000, according to the credits.
- The short made its Cartoon Network premiere on May 28, 2001 as part of the Tom and Jerry: Slamfest Memorial Day marathon.
- The short also aired on May 25th, 2002 on the Kids WB! block.
- This was the final Tom and Jerry production to be produced by Hanna-Barbera Productions before the company was absorbed into Warner Bros. Animation on March 12, 2001.
- This is the first Tom and Jerry cartoon that was made 9 years after the critically panned Tom and Jerry: The Movie as none of the aspects from that movie were to be reused after explicitly dismissing them from the series.
- Unlike most modern Tom and Jerry productions since the 1990s which use the character designs from the late-1940s/early-1950s cartoons, this short uses the character designs from the 1975 series.
- Because of this, Tom doesn't have the grey line separating his eyes from the late 1940s-early 1950s cartoons which was removed later in the Hanna-Barbera run and was not used in any of the eras after, but was reintroduced in Tom & Jerry Kids.
- This short was not released on any home media.
- Director Karl Toerge and musician J. Eric Schmidt who worked on this short, previously worked on Warner Bros. Animation's cartoon series The Sylvester and Tweety Mysteries. J. Eric Schmidt would return to compose music for the direct-to-video film Tom and Jerry: The Magic Ring.
- Due to the negative reaction of Tom and Jerry: The Movie, both Tom and Jerry are reverted back to being "mute" from now on.
- It is the first and only time that Joseph Barbera had a voice role.
- It is the 162nd short overall in 34 years.
