Is my enclosure big enough?
Enter an animal and the space you have. You get a verdict on welfare grounds — floor area and height for land animals, volume and swimming length for fish — not a gallons number that treats a hamster like a goldfish.
Where the recognised standards disagree, you will see all of them. For a Syrian hamster they range from a large retailer's stated minimum to more than five times that figure, and pretending otherwise would be the dishonest part.
Minimum enclosure sizes, every species we cover
These are the figures the checker compares your enclosure against. Where the recognised standards disagree — and for the popular small mammals they disagree by a factor of five — the tool shows all of them rather than quietly picking one. A species whose minimum we have not recorded says exactly that; it is never filled in with a plausible number.
Small Pets — 36 species
Reptiles — 41 species
Freshwater Fish — 47 species
Saltwater Fish — 34 species
The other five
Can it eat that?
Staple, occasional, rare treat or never, with the reason. An unlisted food comes back "not on our list", never a guess.
Open tool →What does it really cost?
Setup, monthly, first year and lifetime, itemised — with electricity worked out from real wattage.
Open tool →Which of these two is easier?
Two species on identical axes: space, company, cost, lifespan and daily time.
Open tool →Is this ammonia reading dangerous?
Free ammonia from your kit's total, the pH and the temperature — the number that actually harms fish.
Open tool →Is this bedding safe?
Safe, caution or avoid for the animal you keep, and why.
