My seven year old was able to complete this build independently. It was several hours worth of building time. In addition, my children have played imaginatively with the completed build.

I don't normally review Lego sets, but this set is definitely worth purchasing. It has so many nods to cat life! Playability is 100% My little one is enthralled with the hidden litter box at the bottom complete with "potty" pieces. We really just bought it for the cute kitties, but everything about it is great. We even had a few extra pieces and were able to make a toy wand. Would highly recommend to any cat lover out there. The colors are nice, and I think would even be a nice addition to tuck onto a shelf with a botanicals set.

My daughter loved this set! Glad to get it at a discount.

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.

[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.

My granddaughter love this. I will definitely order more of these!!
