Vetark Zolcal-D is a veterinary-grade oral liquid supplement designed to prevent and correct calcium and vitamin D3 deficiencies in reptiles, terrarium animals, cage birds, ferrets, and small rodents. It can be administered directly, added to drinking water, or applied over food — making it straightforward to use even with animals that resist handling.
Why Calcium and D3 Matter
Calcium and vitamin D3 deficiencies are among the most common and serious dietary problems seen in captive reptiles. Without adequate levels, animals are at real risk of metabolic bone disease and other debilitating conditions. Zolcal-D addresses both deficiencies in a single liquid formula, making it useful both as a preventative measure and as a treatment where deficiency has already taken hold.
How to Administer
- Give orally by direct dosing into the mouth
- Add to drinking water for passive supplementation
- Sprinkle or drizzle over food at feeding time
Suitable Species
Formulated for use across a broad range of small animals including terrarium reptiles, cage birds, ferrets, and small rodents. It is particularly relevant for reptile keepers managing species with known calcium or D3 requirements, or those recovering from illness where nutritional absorption may be compromised.
