### **Nursery**&#x20;

**Epoch duration: 6 hours**

Deposits/withdrawals of $CAT into/from the Nursery will _lock $CAT for 6 epochs and $KITTY rewards for 3 epochs_.

$KITTY rewards claim will lock staked $CAT for 6 epochs and the next $KITTY rewards can only be claimed 3 epochs later.

_Distribution of $KITTY during Expansion:_

* **80%** as reward for Nursery $CAT stakers.
* **15%** goes to DAO fund.
* **5%** goes to dev fund.

**Epoch Expansion:** Current expansion cap base on $KITTY supply, if there are bonds to be redeemed, 65% of minted $KITTY goes to the treasury until it is sufficiently full to meet bond redemption. If there is no debt it will follow max capped expansion rate.

**Nursery UI Available information**

Next **Seigniorage** indicates a countdown timer to the next epoch (each epoch duration lasts for 6 hours).                                                                                                              &#x20;

**APR** refers to the simple returns in $USD value relative to the amount of $CAT staked ($USD value).

_Note:_ _APR fluctuates from time to time and is dependent on certain factors such as:_

* Price of $KITTY.
* Price of $CAT.
* Amount of $CAT staked in Nursery.

**Nursery on Contraction Periods**

The Nursery will **not** mint any $KITTY (_NO REWARDS ON NURSERY_) while TWAP < 1.01.\
\
**Nursery on Debt Phase**

Debt phase take place on the expansion epochs that start after a contraction period where there are still $sKITTYs to be redeemed.

65% of expansion during debt phase is allocated to the treasury fund to prepare for the $sKITTY redemption. This amount is still reserved whether or not $sKITTY holders are redeeming bonds or not. Once the $KITTY in the treasury is sufficiently full to meet all circulating bond redemption, expansion rates will resume to normal.

$sKITTY emitted per epoch during contraction periods can be found on Regulations.

**Shares**&#x20;

Stake your LP to earn $CAT tokens

Shares pools (shares reward) available for 12 months:

* $KITTY-$MATIC LP: 35500 shares.
* $CAT-$MATIC LP: 24000 shares.

**Bonds**

$sKITTY (bond tokens) are available for purchase when $KITTY falls below the peg. If $KITTY’s TWAP is between 1.00 and 1.01, neither $sKITTY nor $KITTY will be issued.

For example, if $KITTY's TWAP < 1, exchange KITTY for SKITTY will be in a 1:1 ratio.

$sKITTY (bond tokens) are available for redemption when $KITTY goes above the 1 $MATIC peg.

To encourage redemption of $sKITTY for $KITTY when $KITTY TWAP > 1.1 and incentivise users to redeem at a higher price, $sKITTY redemption will be more profitable with a higher $KITTY TWAP value, of which $sKITTY to $KITTY ratio will be 1:R, where R can be calculated in the formula as shown below:

\
&#xNAN;_<mark style="color:purple;">R</mark>_ _<mark style="color:purple;">= 1 + \[ ($KITTY (​TWAP price) − 1 ) ∗ coeff)]</mark>_\
_<mark style="color:purple;">Where coeff = 0.7</mark>_
