Cats are notorious low-water drinkers 🏜️ — a trait inherited from their desert ancestors. While wet cat food already contains 70–80% water, many felines still fall short of optimal hydration.
Why this matters:
-
Chronic dehydration can lead to urinary tract infections (UTIs), kidney disease, and digestive problems.
-
Lack of diverse nutrients can result in dull coat, weakened immunity, and sluggish digestion.
Solution? ✨ Add hydration-boosting, nutrient-rich, and vet-approved toppers to your cat’s wet meals.
This guide covers 12 scientifically-backed add-ons, complete with benefits, dosage, risks, and expert insights.
