Plot
Conjoined siblings - one a dog, the other a cat - deal with the unique challenges of their existence. Cat, the more clever of the two, frequently has a plan or a scheme in the works, and more often than not, that scheme goes awry. Together, the brothers face constant ridicule from the Greaser Dogs, as well as from Winslow, a mouse that lives in the wall of their house. Cat longs for fame and fortune, while Dog is happy chasing garbage trucks - a pursuit that always ends with Cat being towed helplessly along as Dog runs headlong after the next truck.

Why It's Considered Hi-Ho-Diggity!

 * 1) The idea of a conjoined cat and dog, while very weird, is interesting.
 * 2) Cat and Dog are both likable characters that have opposite personalities and work off each other very well.
 * 3) Unlike many sadist shows, it decently manages to pull off sadistic humor pretty well.
 * 4) Amusing slapstick.
 * 5) A catchy bluegrass theme song as well as amazing music.
 * 6) Very smooth animation with a neat artstyle.
 * 7) The voice acting is very good, as it utilizes the talents of Tom Kenny, Jim Cummings, and many more.
 * 8) Decent episode plots, such as Cat and Dog trying to sneak back into a taco restaurant they were banned from.
 * 9) It even had a movie called CatDog and the Great Parent Mystery, which reveals Cat and Dog's tragic backstory: they were separated from their foster parents when they were babies.
 * 10) There were many action packed episodes of the series such as "Adventures In Greaser Sitting", "CatDog 3001 / Cloud Bursting", "A New Cat In Town", "Showdown At Hole 18".                       .Had a handful of other great episodes like "Sweet and Lola", "Dog Ate It", "A Very CatDog Christmas" and "CatDog: The Great Parent Mystery" which served as the real series finale.

Bad Qualities

 * 1) As WIR #8 said, considering that this is usually a sadist show, the show is often very mean-spirited with that fact and the duo almost never win at pretty much anything (e.g Cat suffering from the irredeemable mistakes of others, such as Dog's obstinate ignorance for example).
 * 2) Some gross-out imagery.
 * 3) Winslow, the Greaser Dogs, and Rancid Rabbit can be very unlikable.
 * 4) Cat & Dog's personalities are very cliché, especially for 1998.
 * 5) *Speaking of CatDog, they can be very frustrating. Especially with Cat's arrogant, selfish, and petty behavior, and for how Dog's stupidity can get annoying and predictable in an irritating way.
 * 6) Some bad episodes such as
 * 7) "War of the CatDog"
 * 8) "Teeth for Two"
 * 9) "Trespassing"
 * 10) The final episode, "Meat, Dog's Friends", while it did have a good/decent ending, was an awful way to end the show.
