Common questions about small animal care and using our free tools.
Rabbits mature quickly in their first year. Use our Rabbit Age Calculator — enter your bunny's age in months or years and we'll show the equivalent human age and current life stage (baby, juvenile, adult, or senior). As a rough guide, a 1-year-old rabbit is approximately 18 in human years, while a 10-year-old rabbit is around 80.
Guinea pigs need unlimited timothy hay (their main staple), about ⅛ cup of high-quality pellets daily, and 1 cup of fresh vegetables per 2 lbs of body weight. Leafy greens like romaine lettuce, parsley and bell peppers are excellent vitamin C sources. Our Guinea Pig Food Calculator will give you personalized portions based on your cavy's weight and age.
Lifespan varies by species: Syrian (golden) hamsters typically live 2–3 years; dwarf hamsters (Campbell's, Winter White, Roborovski) average 1.5–2 years; Chinese hamsters live about 2–3 years. Diet, enrichment and genetics play a large role. Our Hamster Life Expectancy Calculator gives a personalized estimate for your hamster.
Healthy rabbits fed unlimited hay, fresh leafy greens and quality pellets generally don't need supplements. Unlike guinea pigs, rabbits can synthesize their own vitamin C. However, senior rabbits or those with health conditions may benefit from specific supplements — always consult your vet before adding any vitamins to your rabbit's diet.
Our calculators use established veterinary guidelines and species-specific research. They provide excellent starting points for care decisions. However, individual animals can vary — factors like genetics, environment and health history matter. For precise medical or dosage decisions, always consult a veterinarian who specializes in exotic or small animals.
