Binding of Isaac: Rebirth Wiki

Dead Cat is a passive item.



  • In the context of a Devil Room Devil Room:
    • Taking Dead Cat with 1 or 2 Heart Containers won't kill Isaac because it will set his number of Heart Containers to 1 immediately, saving him from the death that would have resulted from having no Heart Containers. Buying Dead Cat when at 1 Heart Container essentially obtains the item for free.
    • Other Devil Room items can be bought without the necessary number of Heart Containers at the cost of one of the many lives Dead Cat provides.
    • To take multiple Devil Deals, buy a Devil deal item then quickly leave the room before the "item get" animation finishes. This will result in Dead Cat reviving Isaac back inside the Devil Room.
  • Added in Afterbirth Taking Dead Cat as Keeper Keeper or Added in Repentance Tainted Keeper Tainted Keeper will reduce their total number of Coin Hearts to one, meaning they will die upon taking any damage at all. Unless either of them have immediate access to an HP Up item, taking Dead Cat is usually detrimental.
  • Added in RepentanceHolding onto a XIX - The Sun? XIX - The Sun? can be beneficial if at high HP. Using it prior to taking Dead Cat will convert all red heart containers to Bone Heart Bone Hearts for the floor. The bone hearts do not disappear when taking Dead Cat and will all revert back to normal red-heart containers on the next floor (and stay filled if the bone hearts were filled).


  • This item can drop from Super Pride Super Pride.
  • Resurrection items activate in a set order. Dead Cat is Removed in Repentance 2nd / Added in Repentance 4th in this order after Added in RepentanceSoul of Lazarus Soul of Lazarus, 1up! 1up!, and Added in Repentance Lazarus Lazarus' inherent extra life.
  • Removed in Afterbirth Picking this up as The Lost The Lost would not show the number of remaining lives, but will still function.
  • Added in Afterbirth † If picked up as The Forgotten The Forgotten, his Bone Hearts are reduced to 1 but The Soul The Soul's Soul Hearts remain unaffected. The reverse is also true.
  • The lives are added after the "picking up an item" animation has ended, so characters that die while the animation is playing will not be revived by this item.
  • Removed in Repentance The effects of the D4 D4, D100 D100, Missing No. Missing No., or a 1- or 6-pip Dice Room Dice Room will not remove the lives granted by this item.
  • Additional Dead Cats can be picked up during a run, increasing lives well past 9. Removed in Repentance Only the first dead cat counts toward becoming Guppy.
  • Added in Afterbirth † / Removed in Repentance This item counts as 9 items, so if Isaac is trying for an early portal to The Void The Void after beating Mom Mom, this will significantly boost the progress closer to 20 items.
  • Added in Repentance If Jacob and Esau Jacob and Esau take the item, only the brother who takes it will be set to one Red Heart Container on pickup. But if they die, both are resurrected with one Red Heart Container.
  • Added in Repentance If Tainted Jacob Tainted Jacob takes this item after being touched by Dark Esau Dark Esau, he will return to his previous Red Heart total upon reaching the next floor.
    • Dying as Tainted Jacob after being touched by Dark Esau and carrying this item will respawn him in the previous room in his lost form. Making it to the next floor will still return him to his previous Red Heart total.
  • Added in Repentance During the The Beast The Beast sequence, Isaac is respawned on the spot upon death, as opposed to doing so in a previous room.


  • Added in AfterbirthDiplopia Diplopia: Isaac gains 18 extra lives in total.
  • Gold Heart Gold Hearts: Gives Isaac many coins when picked up, due to the amount of hearts lost.

In-game Footage[]

Unlockable Achievements[]



  • The 9 lives gained by the item is a reference to a myth that cats have 9 lives.
  • The item Guppy's Tail Guppy's Tail and the transformation Guppy Guppy implies that Guppy has a white fur on it's tip of the tail while the sprite for Dead Cat does not.
  • The Dead Cat shares the same tuxedo type bicolor fur with Guppy.
    • Despite not having Guppy in its name, this item counts for the Guppy transformation which may imply that Dead Cat is Guppy, or at least was what Guppy looked like at some point.

Bug Bug! Added in Repentance If picked up as ??? ???, Dark Judas Dark Judas, Tainted Judas Tainted Judas, Tainted ??? Tainted ???, Tainted Forgotten Tainted Forgotten, or Tainted Bethany Tainted Bethany while in possession of Bone Hearts, the health bar may become glitched. The actual health amount is correctly set to 1 Soul Heart / Black Heart + all Bone Hearts, but some of the Bone Hearts are incorrectly displayed as half Soul Hearts depending on the situation before picking up Dead Cat. The glitch is only cosmetic and will resolve itself after taking damage, picking up health or touching an item.
