Can rabbits eat spinach?
Spinach is safe, but only occasionally, since it’s relatively high in oxalates (RWAF). The RSPCA and the Royal Veterinary College also say occasionally, and PDSA says in moderation.
How to serve it: washed, a few leaves as part of a varied rotation
Good to know: RSPCA Australia advises avoiding spinach in rabbits with a history of urinary problems – ask your vet if that applies.
Questions
Can rabbits eat spinach every day?
No, only now and then and in small amounts.
Can guinea pigs eat spinach?
Yes, but only a little. Spinach in moderation only: NC State rates it very high in oxalate. Blue Cross also warns about its calcium, though NC State rates its calcium as low.
