Colourful, fun and interactive

Krb293 July 9, 2025

[This review was collected as part of a promotion.] Lego is a favourite in our household and this set did not disappoint! My daughter (7 years) and I put this together in one go, with lots of playing along the way! We always find the visual instructions in the Lego instruction booklets to be very easy to follow - my daughter was able to move through the build without any issues. My favourite part of this set is the mix of colours. My daughter loves the little touches you can add to the characters to personalise them. My 10 year old son has also spend time playing with us. There are some unique parts of the set we haven't seen before - cat balloons, cat party hats, balls of wool and a birthday cake. This is one of our favourite Lego Friends sets we have built so far.

Sooo many pieces but so much fun!

Catmack551 July 4, 2025

[This review was collected as part of a promotion.] What an amazing surprise for our little Annie! She absolutely loves Lego and although she still needs a little help she has absolutely loved seeing it grow and then have heaps of fun playing with all the moving parts and hidden surprises! It took us a good while to build but once it was done she has played for hours with the little characters making little games and stories.

Purr-fect Fun for My Girly Girl

nikunj63835 July 9, 2025

[This review was collected as part of a promotion.] My daughter is a girly girl who loves cute animals and colorful things, so the LEGO Friends Cat Birthday Party & Tree House set was a big hit. She was super excited to build it and did most of it on her own. My younger one also seemed interested even though he is just 3 years old. It was great to see her focused, solving little problems, and adding her own creative ideas. Once it was built, she played for ages, making up stories and party games for the cats. She usually enjoys pretend play, but this set gave her something different — building and storytelling combined. It really changed how I see LEGO for girls. It's not just about building, but also about imagination and fun. I'd definitely recommend it to other parents with girls who love cute and creative play!

Hours of fun

Hann074 June 29, 2025

[This review was collected as part of a promotion.] This product is great. Easy to follow instructions meant that we were able to complete it without my daughter getting board. She has since spent plenty of time over the last few days playing with the tree house. Including other toys in the adventure

Such a cute set

Cn16an3 June 29, 2025

[This review was collected as part of a promotion.] Usually trying to get a few girls together and play nicely is a mission. This set made it an absolute breeze. They all helped on another put it together and played around with the cats. Nugget was the favourite. 100 percent was thoroughly enjoyed by all

Perfect LEGO Set for Cat Loving Kids

Kanwar1 July 10, 2025

[This review was collected as part of a promotion.] Got this LEGO Friends set. It's a fun little build, super cute details with all the cats and mini stuff. My kid loved it and played for hours. Only wish it had a few more figures, but still totally worth it.

Fun for the family

Jask881 July 23, 2025

[This review was collected as part of a promotion.] The family and I loved building this. The kids loved how vibrant the lego pieces are and how they got to put everything together. Building the structure was very straightforward thanks to the clear instructions. There were extra pieces if required. We've got little ones around, I'd recommend keeping the lego pieces away from them as they're small and can be swallowed. We we're able to put everything together fairly quickly without bub feeling left out. I'd highly recommend the set for a family looking for a fun activity together

Endless fun for the whole family

Jacko9 July 18, 2025

[This review was collected as part of a promotion.] The LEGO Friends Cat Birthday Party & Tree House is an awesome LEGO set to have as there are over 300 pieces so it kept my little one busy while having cute characters like the cats and the birthday cake to decorate. I think the adults were even more hooked into it then the kids !
