Why pack size matters
Choosing the wrong weight band can underdose or overdose your pet. The right pack keeps protection safe and effective.
Quick ways to weigh at home
Bathroom scales. Weigh yourself, then weigh yourself holding your pet. Subtract the difference.
Cat carrier trick. Weigh the empty carrier, then pet plus carrier. Subtract.
Keep a note. Record today’s weight in your phone so you have it next month.
Three-step selection
Weigh today. Do not guess or use last year’s weight.
Open the product page. Pick the weight band that covers your pet’s current weight.
If your pet sits between bands, ask your vet or contact us for guidance before you choose.
Puppies and kittens
Growing fast means weight bands can change quickly. Recheck weight before each dose.
Do not stockpile many months ahead for fast-growing pets.
When to recheck weight
After a growth spurt, diet change or desexing.
If your pet looks leaner or heavier than before.
Before switching between a chew, spot-on or collar.
Common pitfalls to avoid
Splitting one dose between two pets. Unsafe and ineffective.
Using dog products on cats. Never do this.
Guessing sizes for visiting or foster pets. Weigh first.
Dosing late. Set phone reminders so you do not miss dates.
