Our tastiest flavor yet is made with freshly-ground hazelnuts! Extra-picky squirrels will love these blocks and you can feel confident that your squirrel is still getting the nutrition they need. Hazelnuts Blocks are vitamin-enriched supplements that contain the vital nutrients your squirrel needs to stay healthy and happy. Hazelnuts Blocks are baked fresh daily with 100% natural, high-quality ingredients by people who care.

Henry’s Difference

Henry’s Blocks are the only natural supplement made especially for your squirrel’s diet with 100% of the vitamins and minerals they need to avoid common diseases like Metabolic Bone Disease and promote bone and organ health. Unlike other rodent/pet foods that are dry and flavorless, Henry’s Blocks are freshly baked daily with only 100% natural ingredients and no preservatives, fillers, or artificial sweeteners.

Henry’s Blocks are a tasty and delicious way to give your squirrel the nutrition they need. Blocks are perishable and must be frozen upon arrival!

Feeding and Storage Guidelines: One bag contains enough Healthy Blocks to feed an average-sized adult squirrel for one month. Blocks contain no preservatives or fillers and must be kept frozen.

  • Adult Squirrels: Feed 2-3 blocks per day.
  • Flying Squirrels, Adolescent Squirrels, Rats, and Mice: Feed 1-1.5 blocks per day.
  • Blocks must be stored in a freezer to preserve freshness. Blocks can be kept in the freezer for up to 6 months, but the blocks will begin to lose their flavor after the first 2 months. 
  • Ensure the bag is firmly resealed after each opening - exposure to air can lead to freezer burn. 
  • To serve blocks thawed, a few blocks can be pulled from the freezer and kept in the refrigerator for a couple of days at a time.

Perishable - Freeze Immediately Upon Arrival!

Made in the USA.

    I feed Hazelnut Blocks to my rehab squirrels along with healthy vegetables to ensure they have a good diet. The squirrels love the Hazelnut Blocks and all of Henry’s other nutritious blocks. Great packaging that can be stored in the freezer.
