I've got 12 guinea pigs all of which LOVE their toys I can't keep a toy for over 2-3 weeks usually! Any hay or twig type toys are gone in a couple of days, barrel roller toys are usually gone within a week or two, homemade toys are done in a day, Nut Knot Nibblers last me a few weeks, and Loofa toys usually don't last long either! Anyone else with guinea pigs that destroy their toys?
