My 3yo sulcata started passing red urine along with urate material. This began when I started feeding a softer hay. When I soak the hay it sometimes has a red tint coming off of it. The hay is by Kaytee (orchard). She is otherwise acting and eating normally...... any ideas? I rotate Tim hay, orchard grass hay and have used some bluegrass hay....I always soak it slightly. She gets a few greens (dandelion/escarole), hibiscus, grass and cactus (which I grow).
