Cats and aquariums don’t always mix well. A swish of a tail, a curious paw on the glass, or a leap onto the stand can spell trouble for both fish and furniture. It’s no wonder so many cat parents start searching for a cat-proof aquarium—something strong enough to stand up to feline curiosity without turning fishkeeping into a full-time job.
That’s where the biOrb by OASE comes in. Built from tough acrylic and designed with enclosed, modern shapes, these aquariums are stylish, durable, and surprisingly easy to care for. In the sections below, we’ll look at what makes the biOrb different, the models available, how much they cost, and whether they truly live up to the promise of being cat-proof.
Why the biOrb Is a Game-Changer for Cat Households
What makes the biOrb so special? It’s not just a pretty face. This aquarium line was designed with safety, strength, and simplicity in mind. Made from acrylic (which is up to 10x stronger than glass), the biOrb is far more durable and resistant to cracks, chips, or catastrophic tumbles than traditional tanks. That means curious kitties don’t stand a chance at knocking it over.
And while it’s protecting your aquatic life from your furry hunter, the biOrb is also winning major points for style and convenience. Every model includes built-in filtration, lighting, and easy access for maintenance—making it one of the most beginner-friendly aquariums around.
The Built-In Filtration System: Low Maintenance, High Performance
One of the biggest reasons pet parents avoid fish tanks? Maintenance. But the biOrb changes the game with its advanced 5-stage filtration system. It starts cleaning right at the bottom—where fish waste and debris collect—and circulates water continuously to maintain crystal-clear conditions. All you need to do is replace the filter roughly once a month.
Translation? Less mess, less stress, and a healthier home for your fish—all while your cat watches from a safe distance.
Acrylic Advantage: Tougher Than Glass and Built to Last
Unlike traditional glass tanks, biOrb aquariums use a special acrylic blend. It’s stronger and 23% clearer than glass. That means you—and your cat—get a better view of your aquatic setup without sacrificing durability. It’s also insulated better than glass, which means your tank stays at a more stable temperature with less energy usage.
Plus, there are no sharp corners or fragile seams for cats to pry open. Every biOrb design is fully enclosed or seamlessly shaped, minimizing opportunities for mischief.
biOrb Models and Sizes: Find Your Perfect Fit
Whether you want a statement piece or a compact tank, biOrb has a model to suit your space and style:
Sizes are listed in U.S. gallons (G). Metric equivalents: 4G ≈ 15L, 8G ≈ 30L, 16G ≈ 60L.
How Much Does a biOrb Aquarium Cost?
You might expect a futuristic, cat-proof aquarium like this to cost a small fortune—but the price tag may surprise you. The biOrb Classic line often starts at under $100, making it one of the most accessible premium tanks on the market. From there, prices scale up depending on the model and size.
For example, the smaller biOrb Classic 4G (15L) often runs in the $80–$100 range, while the mid-sized biOrb Halo 8G usually falls closer to $200–$250. Larger designs like the biOrb Life 16G can retail for $400+—but savvy shoppers often find better deals on Amazon compared to specialty pet stores or Google Shopping listings.
Overall, you’re looking at a range of about $80–$500+, with the Halo 8G landing in the sweet spot for most cat households. While these aquariums cost more upfront than a basic glass tank, their durability, low-maintenance design, and cat-proof build make them a smart long-term investment.
Is the biOrb Really Cat-Proof?
Yes! Between the sturdy acrylic build, fully enclosed design, and rounded corners, the biOrb is about as close to cat-proof as an aquarium can get. Your cat may still watch the fish intently or tap the sides out of curiosity, but toppling the tank or reaching inside? Not likely.
For extra peace of mind, place your aquarium on a wide, stable surface and consider a model like the Halo, which has a sealed top and hidden waterline that makes it especially secure. Cat owners often enjoy years of peaceful fishkeeping, even with multiple cats.
