The above measurements are taken manually and may have slight discrepancies. Different-sized fish tanks have different capacities. Glass thickness: 8mm outer, 6mm inner for all models.
🐱 Choosing by Cat Size
All standard models (V1, V2, V3) support cats up to ≤18 lb / ≤8 kg. For multi-cat households, the V3 Tunnel lets cats take turns walking through.
📐 Custom Dimensions
Need a different size? All outer, inner, entrance, and stand dimensions are fully customizable. Custom dimensions have no cat weight limit. Simply place your order and specify your custom dimensions in the message field at checkout.
🏠 Placement Tips
The V1 requires our custom stand. The V2 and V3 work on any sturdy, flat surface that can support the weight. Ensure at least 5 cm clearance on each side for ventilation and maintenance.
📦 Larger Sizes Available
All glass models also come in Large (100×50×60 cm), XL (120×60×70 cm), and fully Custom sizes. Larger tanks have proportionally greater capacity and can accommodate bigger cats.
Model Details
V1 — Bottom Entrance Cat Aquariums
Our first and most beloved design. Two circular entrance holes at the base allow cats to enter from below through the custom stand. Place a soft cushion inside for maximum comfort.
V2 — Front Entrance Cat Aquariums
An arch-shaped entrance in the center of the front panel. No special stand required — works on any sturdy cabinet. Supports the largest cats of all models (up to 19 lb).
V3 — Internal Tunnel Cat Aquariums
Entrances on both sides create a walk-through tunnel. Connect multiple units for an extended underwater tunnel system. The most interactive design for curious cats.
