Pros: sturdy, compact, has sisal posts
Cons: this cat tree is not for adult cats, but is great for young kittens
i'm not a fan of Go Pet Club cat trees. this is because when looking at their cat trees online, i've found some of the heights of the trees in their listings to be not exactly accurate and (as in this cat tree) i feel their listing ought to be clear that the particular cat tree is really too small for an adult cat/is suitable for young kittens.
i bought this small cat tree for my two adult cats. we already had a couple large cat trees, but i thought this small one would work well as an addition to place in a limited space.
the tunnel at the top of the cat tree is large enough to allow an adult cat to fit inside it, but the lower shelf/lounger area is way too small for an adult cat. the sisal posts were well-made, but not tall enough that my adult cats were interested in scratching on them. the horizontal sisal post inspired no interest from my adult cats either. however, they did use the top of the tunnel to sit on.
all that being said, this Go Pet Club 28-inch cat tree is a purrfect size for young kittens. my neighbor and i rescued a litter of abandoned very young kittens from some nearby overgrown property, and i brought this small cat tree over for them to use/play on. those young kittens climbed and played all over that cat tree, and were having a ball! this was right in the middle of kitten season, but we were able to find a shelter that would take the kittens and care for them. this Go Pet Club cat tree was among the cat related items that my neighbor and i sent along with the kittens to the shelter.
i based my rating and value for this cat tree on it's use for kittens, not adult cats. but also took into consideration that i feel Go Pet Club's listing for this cat tree wasn't as clear as i felt it should be.
