Adorable
[This review was collected as part of a promotion.] My neice was so happy when I gave this to her. This is a super cute set and she's having so much fun putting it together it seems pretty easy for her to figure out at 7 years old

Fun Lego set
[This review was collected as part of a promotion.] My girls, ages 5 & 7, loved Cat Birthday Party and Treehouse set. Our household loves Lego products. The set has easy to follow directions, and the bags that come numbered make for an easy to understand assembly. There are no sharp edges or any worries that I have with the Lego sets.

Adorable and easy to use
[This review was collected as part of a promotion.] This was so cute! My child love building and rebuilding this set. The directions were not hard to follow and the pieces went together nicely and did not put up much fight to separate.

Great LEGO set for cat lovers!
[This review was collected as part of a promotion.] We love the Lego Cat Birthday Party & Tree House set! My daughters (ages 4 and 8) have continued to use these as play sets, which means they get taken apart often. Luckily, assembly is so easy with this set. The different colors of each section of the tree house make it a snap to put back together. My only suggestion would be to make a similar Lego set that is similar to this for younger ages, as my toddler enjoyed the set most and required supervision due to part size. Still, it's a great set and also makes a great decoration for daughter's homeschool desk.

Cute, challenging and fun
[This review was collected as part of a promotion.] My 9 year old daughter loves this Lego set, a lot! It’s colorful, fun and will keep her occupied for a little while. We love doing things like this as it’s a fun challenge that makes her pay attention to detail! 9/10
