Daisy, my chinchilla, is very fussy about her hay. So far the only one she'll eat is Oxbow timothy hay, not even other brands... until this one! She's now approaching 18 years old, so we've had years to try her (and her sister, who died last year, sadly) all kind of brands and we've now found one she actually seems to prefer. She does have 24hr access to the hay but she looks forward to her handful of fresh Nibble & Gnaw in the morning whilst she's still in bed... not that she's spoiled or anything... ;) I've attached a photo of her in her bed, she sticks her nose in the camera so I can only capture her when she's sleeping, not eating.
