Separate calculators for each pet type
Cats, dogs, rabbits, hamsters, guinea pigs, birds, reptiles, turtles, and fish each need their own lifespan context. Start with the right calculator, then review the sources behind the result.
- Cats, dogs, rabbits, hamsters, guinea pigs, birds, reptiles, turtles, and fish are handled separately instead of sharing one generic formula.
- Core lifespan numbers come from reviewed rules and listed sources.
- Rabbit, hamster, guinea pig, bird, reptile, turtle, and fish calculators show clear limits when the evidence is less complete.
- Results stay educational, avoid exact death dates, and do not replace veterinary advice.
Lifespan guides and research
