Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
Cat liked it so much the strings wrapped around the middle lasted less than 30 seconds (as can be seen in the video taken just after it arrived!). If the middle part was a ball of string rather than strings wrapped and glued it would be better. Shouldn't have been surprised as other reviews indicated this happened quickly but lived in hope it wasn't this quick!
After the rave reviews I was so looking forward to getting this. Unfortunately the cat couldn't care less. Could be the crinkle noise inside I realise now the cat doesn't like. I'd try it again if there was a version without this. It's well made and looks great, I'll give it to another cat owner and they may have more joy.
