Water delivery is the single most consequential accessory decision for a Campbell. Sipper bottles remain the default choice in most setups because they keep water clean, prevent substrate contamination, and allow easy volume monitoring. A good bottle for this species holds 4 to 8 ounces, has a stainless steel ball valve at the tip, and mounts inside the cage at a height the animal can reach comfortably while standing. Glass bottles last longer than plastic and resist chewing; plastic bottles are lighter and easier to hang but can develop biofilm faster.
Water bowls are an alternative gaining traction in the husbandry community. A shallow heavy ceramic dish, positioned away from the wheel and away from substrate-disturbing toys, more closely matches how the animal would drink in the wild and avoids the small risk of ball-valve failure that can leave a hamster without water overnight. The tradeoffs are substrate contamination and the need to refresh water at least daily. Many keepers offer both and let the animal choose.
Food dishes for this species are largely optional because scatter-feeding and foraging delivery are preferable to bowl feeding. When a dish is wanted — for measured pellet portions, for example — a heavy ceramic or stoneware dish that cannot be tipped is the right choice. Plastic dishes get chewed and flipped; lightweight dishes get buried in substrate. Position the dish near but not directly under the water source to keep food dry.
Replacement and cleaning frequency matters more than purchase price. Water bottles should be emptied, refilled, and externally rinsed daily; the inside should be brush-cleaned weekly to prevent biofilm buildup. Food dishes are washed weekly with hot water and an unscented mild detergent, then thoroughly dried before reuse. Avoid scented dish soaps that can leave residue an attentive hamster will detect and reject.
