Squirrel Blocks
Made from all-natural, 100% human-grade ingredients, Henry's Blocks™ are the essential supplement for your squirrel's diet. Developed specifically for squirrels, Henry's Blocks have all the vitamins and minerals squirrels need to promote and support bone and organ health, while helping to avoid common ailments like Metabolic Bone Disease (MBD).
Henry’s carries a broad and growing range of premium rehab supplies. With everything from probiotics and vitamin and mineral supplements to non-auto-shutoff heating pads, rodent-size e-collars and much more, Henry’s is here to support you and the animals you care for.
Our little ones LOVE these. They like fresh veggies, too: radicchio, broccoli, avocado, bok choy, etc... But, fresh produce just isn't enough for a healthy indoor life. The picky blocks provide additional vitamins and minerals that are vital for rescues!
Having lost one to MBD, we learned this the hard way. I'm writing this review to hopefully help others to avoid that.

We have tried the other blocks, and these are Bella's favorite, and she must pick the block she is going to eat. I'm so glad she gets something healthy to eat.

Bella, my sweet 6 month old squirrel loves these. I only wish they were in smaller pieces so I didn't have to break them apart, but that is a human issue not a squirrel issue. Lol

10 out of 10 highly recommend!
10 out of 10 highly recommend! The sampler pack is such a great way to discover which blocks your squirrel will enjoy the most! My little Aspen is a very picky eater so I try to order the sample pack every two months to see if his taste buds changed and every time I order the sampler pack we find a new flavor that he enjoys! These blocks are great, thank you Henry's healthy pets for keeping our squirrels alive, alert, active and healthy! I don't know what I would do without my little Aspen and you all make it very easy on us squirrel parents! The moment he even hears the bag crinkle he runs and is ecstatic and tries to steal the entire bag from me! 😂 if you're having trouble finding which blocks are perfect for your squirrel baby look no further!! This sampler pack will definitely help you discover which flavor blocks your squirrel enjoys! Don't order an entire bag of blocks if you're unsure which flavor your squirrel enjoy because again, some squirrels are picky eaters like mine! I know I'm the type of person to order one thing and if my squirrel doesn't like it, I won't order again, but with the sampler pack, I don't have that problem. I will continue ordering from Henry's pets and there is no other place I will purchase blocks from my squirrel!! Aspen says "THANK YOU!" And so do I! :)

Flyer Approved!
A 5 week old flying squirrel came running on our porch screaming for its little life. Our kitty’s were about to get it:(. After no luck of finding someone to take it, I found the goats milk substitute and I was able to feed that somewhat fine but overnight shipped this fox valley 20/50 along with picky blocks. Just from the first feed on fox valley I noticed a very positive change in the flying squirrels food drive! I was having no luck with solid food at all until I gave a small piece of picky block. Instantly nosed and ate it up. Very happy with the results I’m getting from this food. Excited to weigh the little one again and see the progress!

They like it!
Wasn’t sure what to expect - had read a lot of reviews about what to feed squirrels & everything said to feed blocks but that squirrels don’t really want them/like them. This was the first block we tried and both squirrels loved them. Would recommend

Life Saving!
Someone brought us a couple of baby squirrels and some goat replacement formula to feed them. Both squirrels had diarrhea and one was getting very sick/dehydrated. We bought the Wombarro formula & had it rush delivered. The formula literally saved their lives. Both of them took to it immediately, the diarrhea cleared up quickly and both of them started thriving.
The formula came in quick and in good condition. Very happy customer & squirrels! 100% recommend

Looking Ahead
A few dates and seasonal reminders worth keeping on your radar.
Squirrel Appreciation Day — January 21, 2026 🐿️
National Moose Day — January 25, 2026 🫎
As winter comes to an end, seasonal wildlife patterns begin to shift. Opossum and bear babies may start arriving as early as February, which means the next rehabilitation season isn’t far off. This is a good time for wildlife supporters to keep the months ahead in mind and be prepared.
Fun Fact of the Month
Mother squirrels don’t rely on just one nest. They build several and will move their babies if a nest is damaged or no longer safe.
