Pros: Well made and easy to see these little mice are eye catching and last well.
Cons: Small so disappear regularly. Expensive for what they are.
Mouse was initially interested in these as they came out of the packet but they didn't hold his interest any longer than any other toy mice. He didn't claw and chew at them to get any of the intended teething and dental benefits from the design so I can't say whether the design was effective. They have been used like the majority of Mouse's little toys, for throw and chase games but he didn't favour them enough to use them for fetch.
They are small and as a result got lost very frequently as soon as they are batted around the floor. They will go missing for months on end and I eventually seem to find them wedged under some bit of furniture or other. They still look pretty much like new and although you can look and see they are well made I also think their condition relates to how little they have been played with. They were significantly more expensive than other toy mice and I do not feel they gave value for money. Shame as the potential dental benefits seemed like a good idea.
