Not Enough Kittens Features

Despite Not Enough Kittens being completely bonkers in design and style, the features are quite basic. There is a free spins round that can award up to 25 free spins with the potential to win additional scatters.

Aside from that, symbols can double up provided that there is a wild in the winning payline. Ultimately, this means that you can win even more with double symbols!

Not Enough Kittens - Wilds


Landing a single cat symbol in a winning payline with a wild will end up doubling in pay for a bigger payout. In the bonus game, all wilds are stacked and can substitute any symbol except the scatter.

Not Enough Kittens Review

One day, a professor at P.U.S.S facility decides that the world didn't have enough kittens and that she needs to create even more. Not Enough Kittens is a completely bizarre slot that can only be defined as WTF. It contains a madwoman and her desire to completely fill the world with kittens. 

Developed by Thunderkick, this animal slot plays on 5-reels with 35 paylines and gives players the potential to win up to 3,650x their stake. Featuring double symbols, free spins and retriggers, Not Enough Kittens is definitely a 'fur-midable' slot.


The setting of this slot is some strange laboratory with different vials and animals surrounding it, but there is also typical 'cat lady' decor. On top of the reels is the infamous professor who looks like a crazy cat lady with her twitching eyes and general dress sense.

It will come as no surprise that the reels themselves are a conveyor belt of kittens and wool balls that can double at any time. Most of the cats are adorable and cute, but the white one is just terrifying. It's impressive that each of the kittens has different animations and their own personality through that.

As expected, there are meows and a lot of cat noises. Thankfully they are cute and blend well with the soft 'elevator' music playing to make the slot feel a little more relaxing. The whole slot is basically a hot mess that strangely works.


Whilst the whole concept of this slot is utterly bonkers, the gameplay is still easy to follow. The extra games include free spins and symbols doubling - which isn't uncommon in online slots.

Any menus can be found at the bottom of the reels with the autospin, bet level and spin button is found at the far right. Just like in most other Thunderkick slots, this one contains up to 5,000 autospins! Settings such as sound or the paytable are to the far left in a secondary menu.

Win Potential

With a decent RTP at 96.10% and a low to medium volatility level, Not Enough Kittens is great for newcomers to online slots. The payouts we experienced were fairly frequent but low and we found that we triggered the free spins round a lot.

Now to gain the 'big meow' (aka big win), you need to double up your cats and fill the reels with wilds! This could lead to the maximum payout of 3,650x stake.

Our Verdict

It's not very often that you find a crazy game that clones kittens - but that's the case with this slot. Thankfully, the gameplay and overall design of the slot is pretty impressive too. Of course, it all comes down to the win potential and for a low to medium volatility slot, 3,650x your stake is a pretty solid payout.

Whilst Not Enough Kittens won't be a landmark in the slot community, it's an unusual slot that is 'purrfect' for animal lovers and newcomers to online slots. Don't be a sourpuss, check out Not Enough Kittens for a wild ride!
