Notes and Trivia
thumb|300px|right|Cat House WB Trailer
 * The title of the episode comes from the Russian fairy taile "Koshkin dom" ("Cat House").
 * Although Prue's appearances are from archive footage of earlier episodes, and only her back was shown, this was the only episode to feature all four sisters.
 * Phoebe says to Paige that for a long time, she, along with Piper and Prue, didn't know that Kit was their familiar, until they battled the warlock-familiar Shadow in Pre-witched.
 * Kit was previously referred to as "him" in Pre-Witched. Now Kit is shown as a female (She is called "she" in cat form, and her human form, Katrina, is female, as well.)
 * The disappearance of the bride and groom wedding cake topper foreshadows the break up of Piper and Leo in the next season.
 * Although Prue's back is shown in the wedding flashback, this is not Shannen Doherty. A stuntwoman filmed the original scene and the flashback was able to be used in this episode, because it did not violate Shannen's contract over using her likeness.
 * In the memory in which Piper heals Leo, Piper orbs away with Leo. This could be seen as a mistake, however, since this is a memory, it could be that Piper and Leo remembered it wrong.
 * Cole appears in a flashback during the memory of Piper's and Leo's wedding.
 * The house that Katrina lives in, in this episode was used in Beverly Hills, 90210, a 90's teen soap show that Shannen Doherty starred in.
 * We find out in this episode that Piper was engaged to the warlock Jeremy. Previously it was only known that they dated.
 * This episode scored 4.2 million viewers.
 * The UK title for this episode is "Flashbacks" - in reference to the sisters taking a walk down memory lane, in a flashback style.

Glitches

 * Leo seems to remember their first kiss, but while they did this, Piper was under the truth spell, so Leo shouldn't have remembered it. Although it could be that, because he's a Whitelighter, the spell didn't affect his memory.
 * Paige's necklace is removed during the orbing scene.
 * In They're Everywhere, it is said that warlocks don't bleed. However, Katrina draws blood when she scratches the warlock's face in this episode.
 * When Phoebe and Paige went back to Leo proposing to Piper the first time, Paige wanted to hear the answer before they left, but Phoebe told her they already knew the answer. This is somewhat a mistake since Piper turned Leo down that time.
 * In Just Harried after Prue's astral projection self ruined the wedding, Phoebe went and tried to calm Piper. When Phoebe was heading toward Piper, she stepped over Prue's body. In Cat House, the same thing happened except Phoebe didn't step over Prue's body when she was heading toward Piper.
 * In Just Harried, the guy on the motorcycle said something different than the guy on the motorcycle in Cat House. Also the guy on the motorcycle in Cat House voice is deeper than the one in Just Harried.
 * When Piper healed Leo, he later orbed. This is a mistake because Piper switched powers with him.
 * In the memory in which Phoebe and Piper track Dantalian down, Paige says: "Evil? You were blonde!". This should not suprise her, considering the fact that when she meets Phoebe for the first time, Phoebe was actually blonde.
 * Phoebe claims to be unaware that Kit was their familiar, yet when familiars were part of the story previously in Pre-Witched, Phoebe implied that she knew Kit was their familar by saying that she "wouldn't be able to look at him the same way" after dealing with Shadow the former familiar.
