Best Phosphorus-Rich Foods for Guinea Pigs
Ranked by phosphorus content among foods safe for guinea pigs in the Creature Feast catalog.
#1
Peasper 100g: ~108mg phosphorusPeas are the best vegetable source of phosphorus commonly available to guinea pigs. Phosphorus works in tandem with calcium for bone health, and the ratio between the two matters enormously for guinea pigs prone to urinary calculi. Peas have a favorable calcium-to-phosphorus ratio.
#2
Broccoliper 100g: ~66mg phosphorusBroccoli delivers good phosphorus alongside vitamin C and fiber. Its calcium-to-phosphorus ratio is close to 1:1, making it a balanced mineral contributor. The stems contain slightly more phosphorus than the florets.
#3
Timothy Hayper 100g dry: ~200-250mg phosphorusTimothy hay provides a steady phosphorus supply throughout the day. Its calcium-to-phosphorus ratio of approximately 1.5:1 to 2:1 is considered ideal for guinea pigs, supporting bone density without pushing calcium excess toward bladder stone formation.
#4
Pumpkinper 100g: ~44mg phosphorusPumpkin flesh is a gentle phosphorus source that guinea pigs enjoy. It also provides beta-carotene and fiber, making it a well-rounded treat. Feed raw in small cubes — remove seeds and rind, as the seeds are too fatty and the rind is too tough.
#5
Cauliflowerper 100g: ~44mg phosphorusCauliflower is a moderate phosphorus source with a low calcium load, which helps keep the calcium-to-phosphorus ratio in a healthy range. Introduce slowly since cruciferous vegetables can cause gas in sensitive guinea pigs.
