Did you know
Six small things worth knowing.
No. 02
A cat's diet should be ~70% moisture.
Descended from desert wildcats, cats evolved to get water from prey. Dry-food-only diets stress the kidneys over time.
No. 03
An extra 10% body weight cuts ~2 years of life.
Landmark Purina lifespan study (2002) found lean-fed Labradors lived a median of 1.8 years longer than well-fed siblings.
No. 04
Puppies need ~2× the calories of adults.
Per kilogram of body weight. Growth plates close around 12–18 months depending on breed size.
No. 05
Chocolate's danger is theobromine.
Dogs metabolize it 4× slower than humans. Dark chocolate is ~10× more toxic than milk chocolate.
No. 06
Taurine is non-negotiable for cats.
Without dietary taurine, cats develop dilated cardiomyopathy and blindness within months. All complete cat foods supplement it.
