Pet Calculators

Find the minimum recommended cage size and safe bar spacing for your pet bird. Choose the species and how many birds live together to get welfare-based width, depth and height, a flock-scaled volume and a scaled cage diagram.

Work out your cat's daily calorie needs from weight, age, activity level and neutered status. Uses the veterinary RER formula with life-stage multipliers to suggest feeding amounts for both wet and dry food.

Find out how many litter boxes your cats need using the vet-recommended one-per-cat-plus-one rule, adjusted for the floors in your home. Get a floor-by-floor placement plan, a scooping schedule and monthly litter cost.

Convert your cat's age to human years with accurate life stage analysis, health insights, and visual comparison charts.

Estimate a dog's chocolate toxicity risk from body weight, chocolate type, amount eaten, time since ingestion and symptoms. Converts it to a methylxanthine dose in mg/kg, compares it with veterinary thresholds and explains the next step.

Estimate how much food a dog should eat per day from body weight, life stage, activity, feeding goal, meal frequency, treats and the label's energy density. Converts daily calories into cups, cans or grams and per-meal portions.

Estimate a dog's likely lifespan and remaining years from breed baseline, body size, current age, weight condition, activity, preventive and dental care, neuter status and chronic health burden, instead of a generic breed average.

Convert dog years to human years using modern veterinary guidelines. See your dog's equivalent human age, life stage, and health insights based on breed size.

Work out how much hay your horse needs each day from its body weight and activity level, as a percentage of body weight. See the daily ration in pounds or kilograms, flakes and bales per day, week and month, and monthly cost.

Estimate whether pet insurance is likely to save money over your pet's remaining lifetime by comparing projected vet bills against premiums, deductibles, reimbursement rates and payout limits, for a young dog, indoor cat or senior pet.

Find the IATA-compliant travel crate size for flying with a dog or cat. Enter body length, height to the elbow, shoulder width and standing height to get the minimum crate dimensions and the matching standard series from 100 to 700.

Predict a puppy's likely adult weight range from breed profile, current age and current weight on a size-aware growth curve. See the adult size class, growth progress so far, remaining gain and when the puppy should finish filling out.

Build a prey-model raw feeding plan from body weight and feeding percentage, split into muscle meat, edible bone, liver and other secreting organs. Compare classic 80/10/10 with custom ratios and get a weekly shopping list.

Find the right UVB lamp output and basking distance for your reptile enclosure. Pick the species' Ferguson UV Zone and terrarium height, and the inverse-square law gives a basking distance that lands in the target UV Index range.
