No — dangerous
Absolutely not — garlic is roughly 5× more toxic than onion, and cats are the most sensitive common pet. A single clove can sicken a cat.
Garlic is the most concentrated allium: for a typical cat, one clove (about 5 g) approaches a toxic dose of the compounds that cause haemolytic anaemia. “Natural remedy” advice suggesting garlic for fleas or worms in pets is dangerous folklore — there is no proven parasite benefit and a well-proven blood toxicity. Garlic bread butter, garlicky sauces, and supplements containing garlic powder are the realistic household risks for cats.
None — and treat any known ingestion as vet-call-worthy, especially in cats under 4 kg, kittens and seniors. Signs may be delayed by 2–4 days, so don’t be reassured by a normal first evening.
No flavour shortcut is worth it: stick to plain meat or commercial cat treats. See the full cat food safety list.
