Dried Hamster / Rabbit mixes begin to loose their vitamin content within 8 weeks of manufacture and this should be born in mind when considering the need for supplementation, particularly if fresh foods are not offered. Two weeks of Vitamin C deprivation causes skeletal scurvy in Guinea Pigs.
High fat foods, such as peanuts and sunflower seeds should be kept to a minimum to reduce the risk of obesity, particularly in caged pets. Sunflower seeds are low in calcium and have been implicated in osteoporosis and spontaneous fractures in Gerbils fed solely on these. Some rodents (notably Rats) can develop corn allergy, manifesting itself as an irritant dermatitis.
Hard items, such as fruit tree bark for gnawing, should be provided to help keep the incisors worn down and many small rodents appreciate whole nuts in shells, giving exercise for the teeth and relieving boredom. Very hard shells, such as Brazil nuts and Walnuts, can be cracked a little first. Foods should be offered in solid earthenware or ceramic dishes which cannot easily be chewed. Soft plastic if swallowed can harden in digestive enzymes causing damage.
Water should be provided in gravity drinking bottles where possible to keep it free from contamination and prevent small rodents from drowning in open dishes. This water should be changed daily to prevent stagnation and the delivery spout checked for patency.
