Chapter 3 of 9 · Red-Footed Tortoise Care Guide
Feeding, Supplements and Water
Disclaimer: I'm not a veterinarian and I don't hold a degree in animal science or animal care. This guide is compiled from the published sources listed in every chapter. For a sick animal, a reptile vet is the authority.
The short version
- Red-foots are omnivores. Feed about 70% greens and vegetables, about 15% fruit, and under 15% animal protein [4]; a second guide uses about 90% plants and 10% animal foods [1].
- Adults get a small protein portion every 1–2 weeks [3].
- Feed hatchlings and juveniles daily and adults every other day [1][4].
- Dust food with calcium, alternating with a vitamin and mineral supplement, and keep a cuttlebone in the pen [1][3].
- Give a shallow water dish big enough to sit in, and soak hatchlings once or twice a week [2].
An omnivore, not a grazer
This is the biggest difference from Russian and Greek tortoises: for red-foots, fruit in moderation is normal, and a small amount of animal protein is part of the diet.
The wrong diet in either direction causes trouble. Too much fruit and protein leads to diarrhea, pyramiding and kidney strain. A strict grass-only diet leaves them thin and hungry.
What to feed
These rough proportions come from one care guide [4]. Another puts it at about 90% plant foods (leaves, flowers, fruit, grasses and vegetables) and 10% animal protein and mushrooms [1]. Both keep animal protein small.
| Food group | Share | Examples |
|---|---|---|
| Leafy greens, weeds, flowers, vegetables | About 70% | Dandelion, plantain weed, clover, hibiscus leaves and flowers, mulberry and grape leaves, turnip and collard greens, endive, escarole, spring mix (not iceberg), squash, pumpkin, cactus pad, grated carrot, mushrooms [1][2][3] |
| Fruit | About 15% | Papaya, mango, melon, berries, fig, banana (sparingly), cactus fruit. A few bites several times a week, not at every meal [1][4] |
| Animal protein | Under 15% | A small portion every 1–2 weeks for adults [3]: earthworms or other insects, or a commercial tortoise diet with extra protein [2]. Keepers also use hard-boiled egg, snails or a pinch of low-fat dog or cat kibble; this is keeper practice, not tested |
Supermarket fruit, salad and vegetables can make up to half of the diet. Supplements matter most when you rely on supermarket produce [3].
How often to feed
- Hatchlings and juveniles (under about 5 years): daily, as much as they finish in one sitting [1][4].
- Adults: every other day, to prevent obesity [1][4].
Sources differ on how much protein to give. A veterinary factsheet limits it to a small amount every 1–2 weeks [3]; one care guide only caps it at under 15% of the diet [4]. We recommend staying on the low side.
What to avoid
- Spinach, rhubarb, beet greens and large amounts of brassicas (kale, cabbage, broccoli) as staples. They carry oxalates and goitrogens. This is keeper experience, not proven.
- Avocado, onion and dairy. Never feed these.
- Iceberg lettuce.
Calcium and vitamins
- Dust greens lightly with calcium, alternating with a reptile vitamin and mineral supplement [3]. Neither cited guide sets an exact schedule; many keepers dust two or three times a week. Follow the product label and your vet.
- Many keepers use a calcium with D3 for tortoises kept indoors, as a backup to the UVB lamp. Some all-in-one products combine calcium, D3 and vitamins [1]. Use only one D3-containing product, at the label dose or less, because extra D3 on top of good UVB can build up to toxic levels. Ask your vet if you are unsure.
- Leave a cuttlebone in the pen for self-serve calcium and beak wear [1].
Water
Offer a shallow dish wide enough for your tortoise to sit in. Rinse it daily, and disinfect it whenever your tortoise poops in it. Keeping a spare dish makes swapping easy [1][3].
Soaking
Hatchlings dry out quickly. Soaking helps them drink, poop and keep their urates soft.
- Hatchlings and juveniles: 15–30 minutes, once or twice a week [2].
- Adults: a shallow warm bath twice a week [3], or whenever the pen is on the dry side.
Use shallow, lukewarm water, no deeper than the lower edge of the shell [2][3]. Keepers often aim for 85–90°F (29–32°C) (keeper experience, not proven). Check it with a thermometer and stay with your tortoise for the whole soak. Afterward, dry your tortoise off and put it back on the warm side.
