I've been getting these for years and my cats still think they are great. Depending on how fuurrrocious a hunter you have they can get 'gutted' pretty fast. The feathers are as good as any similar product- long enough not to be inhaled and oh so fun to rip out. Despite this, my cats play with the fur until there is nothing left. That took 5 years and was on kittens number 3&4. If you are looking for a toy that stays intact forever, get the jumbo fur mice. If you aren't too bothered by torn-up, ravaged, and well loved toys this knocks it out of the park. My cats seem to like the size- not too big, not too small (I got 'kickers' once FAIL way too big). The catnip 'guts' don't last long but the smell must hang on. I suppose you could put in a catnip 'preroll' by Meowijuana to refresh but my kits don't require it. I do have reservations when it comes to the price but get over it when I know how well used they will be.
