Why Care Calculations Differ by Animal
Every animal has completely unique care needs. A small 4.5 kg (10 lb) dog burns calories much faster per pound than a 450 kg (1,000 lb) horse, cats have strict carnivore protein requirements, and backyard chickens require tailored feed rations to produce fresh eggs. All our tools apply verified veterinary standards calibrated specifically to each animal's size, lifestyle, and life stage. Select any animal below to explore daily feeding guides, ideal weight trackers, and health calculators.
Dogs
Simple, vet-verified tools for dogs and puppies. Calculate daily food portions, estimate your puppy’s adult weight, check chocolate toxicity risk, plan safe weight loss, and track heat cycles.
Cats
Easy calculators for cats and growing kittens. Find the right daily food portions, calculate kitten growth calories, check daily water needs, assess body condition, and track pregnancy due dates.
Horses
Practical tools for horses, ponies, and foals. Estimate your horse’s weight with a measuring tape, calculate daily hay and grain feeding amounts, and track 340-day foaling due dates.
Poultry
Practical tools for backyard flocks and broiler farms. Track daily egg production, calculate feed conversion efficiency (FCR), and plan egg incubation and hatch schedules.
Cattle
Simple tools for cattle and calves. Estimate weight using a heart girth measuring tape, calculate average daily gain (ADG), and track 283-day calving due dates.
Sheep
Practical tools for sheep and lambs. Estimate live weight through fleece with a chest tape, track lamb growth rates, and manage 147-day lambing due dates.
Goats
Everyday tools for dairy goats, meat breeds, and kids. Estimate weight with a chest tape, monitor kid growth, and track 150-day kidding due dates.
Birds
Everyday tools for pet birds, parrots, and canaries. Calculate daily energy needs, check safe feeding, and plan egg incubation hatch dates.
Rabbits
Easy calculators for pet bunnies and rabbit breeders. Check healthy adult breed weights, calculate daily hay and pellet portions, and track 31-day kindling due dates.
Fish & Aquatics
Everyday tools for aquarium hobbyists. Calculate true tank water volume (gallons and liters), substrate displacement, and safe fish stocking limits.
Reptiles
Essential tools for reptiles, bearded dragons, and snakes. Calculate tank enclosure sizing, basking thermal gradients, and proper prey portions.
General & Conversions
Everyday conversion tools and animal vitals. Convert weights between pounds and kilograms, check normal animal body temperatures, and compare pet ages to human years.
