A kitten’s age and measured weight matter more than the word “small” on a shopping page. This guide compares selected currently listed cat products and links directly to their pack options. It is not a recommendation that every kitten needs one of these medicines.
| Product range | Labelled cat bodyweight | Age condition | Listed packs |
|---|---|---|---|
| Stronghold — selamectin | Up to 2.5 kg | Not for kittens under 6 weeks | 3-dose pack · 6-dose pack · 15-dose pack |
| Stronghold PLUS — selamectin + sarolaner | 1.25–2.5 kg | At least 8 weeks | 3-dose pack · 6-dose pack · 12-dose pack |
Stronghold and Stronghold PLUS have different formulations and label conditions. Matching a weight band alone does not establish which treatment is appropriate. Check the supplied pack and speak with your veterinarian about your cat’s health and parasite-prevention needs.
The table follows the Stronghold package leaflet and Stronghold PLUS product information. Follow the label supplied with your product.
For larger weight bands, see medium and large cats. Browse the full Stronghold and Stronghold PLUS ranges, or read about introducing cats and dogs.
