If you want to keep your pets interested in their toys, you can keep the toys fresh by rotating their access to certain toys. Try limiting the number of toys your pet has access to at one time and switching these toys once every week or so. This rotation might make your pet more excited to see the toy again and treat it like you just brought it home from the store. However, if your pet has a comfort toy, you might consider leaving this toy out at all times. A comfort toy is any toy your pet sleeps with or carries around with it throughout the day. These comfort toys can help your animals with stressful situations, such as separation anxiety.
