Westermans Wild Bird seed bells are the best. The garden birds are delighted with my purchase.
My little one loves these
The hay smells fresh and not dusty at all, my guinea pigs wheek uncontrollably excited everyday when they smell me getting their hay and it's really compact there's so much in there. I'll be continuing to purchase hay for them since this is also one of the only stores that sell the brand.
I wanted to buy a different type of treat toy but the stockists didn't have it and so they recommended replacing it with this bristle bone toy. Unfortunately though it has removable parts which need to be unscrewed in order to insert the treat. My dog was able to unscrew the end in the first 5 minutes of playing with it and once she had it off she chewed the screw part as well as the treat rendering the toy obsolete.
I wouldn't recommend it as it could be harmful to your dog to be able to chew the long screw and it's not worth spending the money to only use it once.
My dog loves these balls. Although they are pliable they are strong and great for chewing on. And they last a long time.
