🐈‍⬛🎃 National Cat Day + Halloween week? Winifred has been preparing for this moment all year. No costume required when you’re already serving professional Halloween cat. 👻

In honor of National Cat Day, we’re celebrating all the things we love about our feline patients—their personalities, their independence, their perfectly timed judgmental stares…and their ability to make an empty cardboard box more exciting than anything we could possibly buy them. 😹

And with Halloween right around the corner, Winifred would also like to clear something up: black cats aren’t bad luck. They’re just really, really photogenic. 🖤

Give your favorite kitty a little extra love today—and maybe a treat or two. Winifred insists.

Happy National Cat Day from all of us at Oz Animal Hospital!

Candy is here with a sweet reminder that Halloween candy is for humans, NOT our furry friends! 🍬🍭🍫

While your pets might be tempted to sneak a treat (or an entire trick-or-treat bag 👀), some Halloween goodies can be downright dangerous!

🍫 Chocolate: Contains theobromine and caffeine, which can be toxic to dogs and cats.

🍬 Sugar-Free Candy: May contain xylitol, an artificial sweetener that can cause life-threatening low blood sugar and liver damage in dogs.

🍇 Raisins: Sometimes found in Halloween treats, raisins can cause kidney failure in dogs.

🍭 Candy Wrappers: Even the wrappers can be dangerous, potentially causing choking or intestinal blockages.

🚨 Halloween safety Tip: Keep candy bowls, trick-or-treat bags, and chocolate stashes safely out of paw's reach! If your pet gets into something they shouldn't, contact us or ASPCA Poison Control (888-426-4435) immediately. Don't wait for symptoms!

Happy Howl-o-ween from Candy and your locally owned veterinary team at Oz!🎃

Last week, we had so much fun celebrating National Veterinary Technician Appreciation Week and showing some extra love to the incredible Veterinary Technicians and Assistants who help make Oz Animal Hospital so special! 🥳

Our Technicians and Assistants are truly the backbone of our clinics. From drawing blood and running lab tests to monitoring anesthesia, assisting with surgeries, administering treatments, comforting nervous pets, and giving out an endless supply of belly rubs and treats (arguably the most important job 😉), they do it ALL!

Being a Veterinary Technician or Assistant takes an incredible combination of medical knowledge, technical skills, patience, compassion, and the occasional ability to dodge a flying paw or two. 🐱🐶

As a locally owned veterinary hospital, we know that our people are what make Oz, OZ! We're so lucky to have such a dedicated, hardworking, and compassionate team caring for Chicago's pets every single day.

Please join us in giving our amazing Technicians and Assistants a HUGE round of applause! 👏💛 We appreciate you more than words can say!

Lili would like to shake on it. 🤝

This fluffy little Pomeranian knows that sometimes the best way to win over your veterinary team is to come prepared with impeccable manners…and an irresistible face!

Teaching simple behaviors like “paw,” “sit,” and “touch” isn’t just adorable—it can also help pets become more comfortable with being handled. Getting them used to having their paws, ears, and body gently touched at home can make things like nail trims, exams, and routine care a little less stressful.

Of course, Lili seems to have skipped straight to the advanced course: How to Get Whatever You Want by Looking Extremely Cute. 🎓🐶

She passed with flying colors. 💯

🌈✨ Somewhere over the Rainbow Brite… there are TREATS! 🐱

Rainbow Brite is serving up big eyes, a little sass, and a perfectly timed tongue blep! 😋

We're pretty sure she's already decided that being this adorable deserves a reward. And honestly, who are we to argue? At Oz, we believe a little TLC (and a few well-earned treats!) can make any vet visit a little brighter!

Say cheese… or in this case, Parmesan!🧀

Meet Parmesan, serving up some serious Corgi cuteness with those ears, those little legs, and a gaze that says, “I was told there would be treats?” 👀

Fun fact: keeping your pet at a healthy weight is especially important for breeds with longer backs and shorter legs, like Corgis. Maintaining a healthy body condition can help reduce unnecessary stress on their joints and spine and keep them comfortably on the move.

Regular wellness exams are a great opportunity to check your pet’s weight, body condition, nutrition, and overall health—and make adjustments before those extra treats start adding up.

Although when your name is Parmesan, we understand that saying no to a little extra cheese may be complicated. 🧀😂💛

Charles is serving face, underbite, AND impeccable fashion. 😍

But today, Charles is also here with an important reminder: routine bloodwork isn’t just for when your pet is sick! 🩸

Regular bloodwork gives us a look at what’s happening inside your pet and can help:

🧪 Establish a healthy baseline for future comparison
🩸 Monitor red and white blood cells
🩺 Evaluate liver and kidney function
🔎 Identify changes that may not be obvious during a physical exam
🐾 Track trends as your pet gets older

Pets can be pretty good at hiding when something isn’t quite right, which is why routine screening can be such an important part of preventive care.

Charles’ results? We can’t comment on those—but his underbite is clearly off the charts.💛

We’re excited to be featured on this list of locally owned veterinary clinics!

Going out of town and need a safe, comfortable place for your cat to stay? Oz Animal Hospital offers cat boarding at all three of our locations! 💛

Our team makes sure our feline guests get plenty of attention and care while their humans are away—and if your cat needs medications during their stay, we can take care of that too. 💊🐾

Whether it’s a weekend getaway or a longer trip, you can enjoy your time away knowing your kitty is being looked after by a veterinary team that knows cats. 😻

Jackie’s only question: Does room service include Churu? 😂
