• Europe: Be aware of EU regulations; some active ingredients (e.g., certain formulations of fipronil) may have different approval statuses than in North America. Always check local availability.

Here’s a comparative table of Amazon-branded topical flea treatments (and very similar Amazon/Solimo/Basics products) aimed at medium cats, summarizing the key features, pros & cons. If you want, I can also compare them with name-brand veterinary products to see value vs performance.

Details of Amazon Brand Product:

Product	Weight / Cat Size Category	Active Ingredients	Duration of Protection	Speed of Kill / Onset	Special Features	Pros	Cons
Amazon Basics / Solimo Medium Cats Flea Topical (5-9 lbs), 4-count	Medium cats (5-9 lb)	Imidacloprid + Pyriproxyfen	~ 30 days per application (one dose per month)	Kills fleas within 12 hours; treats fleas, eggs & larvae.	Packaging sometimes “Solimo” or “Amazon Basics”; budget pricing; waterproof after 24-h? (depending on variant)	More affordable than big branded topicals; covers three life stages (adult fleas + eggs + larvae); many doses per pack improves value.	Some users report variable effectiveness; some vials allegedly weak or nearly empty; skin / irritation issues in sensitive cats; may be less effective in high flea infestation environments.
Amazon Basics / Solimo Flea & Tick Topical Treatment for Cats (over 1.5 lbs), 6-count	All sizes cats over 1.5 lb (medium included)	Fipronil 9.8% + (S)-methoprene 11.8%	~ 30 days per monthly dose per cat	Starts eliminating fleas & ticks within ~24 hours	Waterproof after 24 h; kills fleas, flea eggs & larvae, ticks, chewing lice; identical formulation under Solimo / Amazon Basics label	Covers broader pest spectrum (ticks etc.); works for many cats; good number of doses per pack; better for prevention & moderate flea burden.	Some users report flea persistence in very heavy infestation; potential skin irritation; might not act as fast as premium vet-prescribed products; requires strict monthly schedule; wet/damp periods may reduce efficacy if the animal gets wet too soon.
Amazon Basics Medium Cats Flea Topical, 6-count (5-9 lbs)	Medium cats (5-9 lb)	Imidacloprid + Pyriproxyfen (same as first product)	~ 30 days per application per dose, 6 doses in the pack	Fleas killed within ~12 hours; eggs/larvae prevented ‒ similar performance to other Imidacloprid+Pyriproxyfen formulations	Same “Solimo/Basics” packaging variations; often better per-dose cost when buying 6-pack vs 4 or smaller packs.	More cost-efficient; brand consistency; good features for the price.	If application is not perfect (fully on dry skin, parted hair etc.), performance may drop; some inconsistency reported in user reviews; may still require supporting environmental flea control.

Key Takeaways / What To Look For

• Active Ingredients Matter: Products with Imidacloprid + Pyriproxyfen are good for breaking flea life cycles (eggs, larvae, adults). Products with Fipronil + (S)-methoprene also cover similar stages plus ticks/lice in many cases. Veterinarians typically trust these combinations.
• Correct Application & Timing: The flea topical must be applied properly (directly onto skin, in the correct spot, when dry, and allowed to dry fully), and repeated monthly. Missed or sloppy applications reduce effectiveness.
• Level of Infestation & Environment: In light infestions or as prevention, Amazon Basics/Solimo products may work well. In heavy infestations (lots of fleas, outdoor cats, humid/climate favorable), higher potency or veterinary products may outperform best topical flea treatment for medium cats.
• Safety & Sensitivity: Some cats are sensitive; any topical insecticide has some risk of skin irritation. Always follow label, avoid doubling up with other flea products, and monitor for adverse reactions.
