This Slow Feeder provides your pet with 20 minutes of mealtime, rather than the 5 minute period of a regular bowl. This can help to prevent choking. The 31cm*30cm*5.5cm unit has a unique Forage flapper design to further slow eating speed and is constructed with anti-skid base to stop it moving and spilling. The top rack is dishwasher safe. The PP material is free from BPA, PVC and phthalates and is non-toxic and tasteless, being tough and corrosion resistant. Not only does this care for your pet's gastrointestinal health, but mental abilities can also be developed by hiding food in boxes for them to search for while they eat, providing additional pleasure.
