Nectarines are rich in vitamins A and C, as well as fiber, which can be beneficial in small amounts.
Risks
The pits of nectarines contain cyanogenic glycosides, which can release cyanide when ingested.
The skin can also be tough for cats to digest, and the fruit's high sugar content can lead to digestive upset or contribute to obesity if consumed in large quantities.
Suggestions
Offer only small, bite-sized pieces of nectarine flesh, avoiding the skin and pit.
Monitor your cat for any adverse reactions.
Note: even if labeled as safe, any food can potentially cause allergies. When introducing a new food, please feed a small amount and observe your cat for any allergic reactions.
