The One4Life® Slim all-in-one car seat takes your child from birth to big kid with trusted Britax safety, ClickTight® installation, and a slim SpaceSaver™ design. As a convertible and harness-2-booster seat in one, it grows with your child for 10 years. It starts rear-facing with an extended capacity of up to 50 lbs., so your child can ride rear-facing longer.

With a slim outside and spacious inside, the 17.5” seat is designed to fit 3 across* without compromising safety and comfort. ClickTight helps you install with confidence, every time. The base and shell are easy to wipe down for hassle-free cleanup. The car seat cover is safe to machine wash and dry, and it’s naturally flame-retardant with no added FR chemicals. One4Life Slim features a high-strength steel frame, a SafeCell® crumple zone, and a V-shaped tether. As your child grows, you can easily adjust the 15-position no-rethread harness and headrest with one hand. With cooling channels, premium padding, three infant inserts, and built-in armrests, your child will love every ride.

It's funny but cheap
My cat does enjoy chasing the little fluff balls around and then batting them for a few seconds than looking back at me for more. It's good for some good laughs and entertainment but the fluff balls and little plastic shooter are honestly dollar tree level quality. The shooter has one flimsy spring and looking at the placement inside it seems like something that'll fall apart pretty fast. Not worth $11 or $8, this should be >$5 easily.

Dangerous
Size: 30 Pcs
My 1 year old cat loved to chase the balls, but who ever designed these balls should be ashamed of their selves. They balls are to small and easy for the cat to chew on and swallow!!! My cat just got done with an extremely costly surgery because he swallowed 3 of the balls he must of hid them somewhere because he usually did not play with them unattended. Never mind the pain my poor sweet baby just went through. I would never purchase something where somebody has not tested the size and shape of something to make sure that it is safe for an animal, sad to assume that somebody would create such a toy without checking that out and putting a animal through this nightmare. This is the first time in my that I have ever done a review, but I would never want somebody to go through what my cat and I have just experienced. Had to him to the emergency room on a Sunday to a follow up appointment at the vet on a Monday and then another follow up appointment on a Tuesday to redo the ultrasound to on Wednesday another appointment to check them and then him having to go in for an emergency surgery on Thursday. The problem is, he didn’t eat them all at one time so they obviously were sitting in his tummy until he started getting sick and throwing up. I will be checking into this company a bit deeper as well, so please be aware and don’t ever purchase something like this.

All 3 cats say 5 stars!
Size: 100 Pcs
The cats love to chase these balls. And it comes with 100! Which is the perfect amount. So far the gun is still working well. I just find you need to barely put the pom pom in after cocking the gun. If you push the pom pom all the way in, it wont shoot. More often than not though, I just throw the balls for the cats. The gun shoots them very far, the cats enjoy chasing them, but they prefer to jump up and try to catch them, which they cant do when I use the gun
