Can my red ear slider eat cranberries?

Yes, red-eared sliders can eat cranberries, but they should only be given as an occasional treat rather than a regular part of their diet. Cranberries are high in sugar and can be acidic, which may upset their stomach if fed in large amounts. Always ensure that any treats are offered in moderation and as part of a balanced diet that includes leafy greens, vegetables, and protein sources.
