Water Bottle for Small Rodents ZOLUX COSY 500 ml — Top-Fill, Blue

ZOLUX COSY 500 ml is a top-fill water bottle designed for small rodents such as hamsters, mice and gerbils. The 500 ml capacity gives a compact but practical reservoir for daily hydration in home cages and small breeding setups. The bottle features a top-filling opening to simplify refills and cleaning, a cage-mount design that keeps the bottle stable, and a controlled metal ball valve to deliver water on demand. The product is finished in blue and intended for routine use with small mammal enclosures.

Advantages

The top-fill system reduces handling time and makes replenishing water faster and cleaner compared with under-cage refill types. A transparent reservoir allows quick visual checks of water level, and the controlled ball-valve mechanism limits leaks and delivers a measured flow suited to small rodents. The cage-mount bracket secures the bottle in place and keeps the drinking nozzle accessible at an appropriate height for small pets.

Suitable for

• Hamsters and dwarf hamsters
• Mice and young rats
• Gerbils and other small rodents
• Home cages and small-scale breeding enclosures

When it may not be suitable

The ZOLUX COSY 500 ml bottle is not intended for large rodents or species with greater daily water requirements; larger bottles or multiple supply points may be required in those cases. It is designed for cage mounting and may not be suitable when a specific free-roaming or open-water drinking arrangement is preferred.

Key specifications

• Capacity: 500 ml
• Fill type: top-fill opening for refilling and cleaning
• Material: transparent reservoir with colored finish (blue)
• Dispensing: metal ball-valve nozzle for controlled flow
• Mounting: cage-attach bracket for stable placement

How to use

Unscrew or open the top-fill cap, fill the reservoir with fresh drinking water and reseal the cap securely. Attach the bottle to the cage using the supplied bracket so the nozzle is at an appropriate height for the animal. Check the nozzle by observing a few licks or drops to confirm the ball valve is dispensing water. Refill and clean the bottle regularly—daily visual checks and full cleaning at least weekly—using warm water and a brush suitable for the reservoir to prevent biofilm buildup.

What to consider before purchase

• Confirm the 500 ml capacity matches your pet’s daily water needs
• Ensure cage bars and spacing are compatible with the bottle’s mounting bracket
• Decide if a top-fill design and metal ball valve suit your cleaning routine and pet behaviour
• Verify the bottle’s height and nozzle position fit your animal’s size

Usage recommendations

Replace water daily and perform weekly full cleanings; inspect the metal ball valve regularly for wear or debris and replace the bottle if leaks or repeated blockages occur. For multi-animal cages consider adding an extra bottle or increasing capacity to ensure uninterrupted access to fresh water.
