Yellow foam? in bunny cage

[AinaWGSD]

Ok, coming from a different angle, as a tech who works with a veterinarian who's special interest is rabbits, most people actually feed way too many pellets. Pellets are nutritionally complete, but they are also very calorie dense and pellets, not dark leafy greens, are responsible for 95% of the obese rabbits we see. Rabbits, except for young rabbits that are still growing and pregnant/nursing mothers, really shouldn't have free access to as many pellets as they would like to eat. They should be fed a limited amount of pellets, based on their weight and energy needs, as much grass hay as they would like to eat, and yes, a large handful or two of dark leafy greens. Yes, too many veggies can lead to malnutrition if you are mainly feeding lettuces (especially iceberg, but all lettuces have much lower amounts of nutrients than dark leafy greens such as collard, kale, etc) which are little more than crunchy water. But a few handfuls of the nutritious dark leafy greens daily and the occasional vegetable such as zucchini, carrot, etc is part of a balanced diet for rabbits. I don't think there's any harm in cutting out greens to see if that makes a difference, but medically I have never seen anything to support the idea that most people feed "too many" vegetables and that it shortens their lifespan (all of the rabbits I've seen who have lived into double digits have had dark leafy veggies as part of their daily diet for at least most, if not all, of their lives).

I'm sorry, I don't think so. I would think this is the case with a dog, cat, ferret, even a chicken as all of these animals can vomit. However, it is 100% physically impossible for rabbits to vomit. They *might* be able to cough up a little phlem from the back of their throat, but it would not be a sufficient enough volume to cause a puddle of foamy liquid that the OP would have noticed. I've only ever seen one animal that can't vomit (a guinea pig...not a rabbit, but their digestive systems work the same way) attempt to heave, it had bloated and it's stomach twisted, and the poor little thing passed within minutes of being observed trying to vomit. It just isn't physically possible.

if it IS calcium build-up in the urine, also known as "sludge" then the first step is to cut back on pellets and push green veggies and grass hay.
Rabbits should actually only get a couple ounces of pellets,with hay making up the bulk of their daily diet. With 1/2 to 1 cup of veggies per day, dark leafy greens are best. Carrots and other high sugar foods should only be an occasional treat.

Foamy yellow is likely sludge in the urine. We had a rabbit die from this, despite vet treatment. In bad cases, the crystals actually block off the kidneys, leading to organ failure. Lots of exercise is important too.

Another note, if you are walking him on a harness and leash, be very mindful of his legs. Our Patches was startled at a barking dog and broke his leg in 2 places. The leash wrapped around his hind leg and tightened when he started to run. $600 later he was good as new, but it was a long time to keep a rabbit in a cast.

Since we took him off of veggies he has been fine.
I'm sorry to here about your bunny's leg. That must have been unpleasant. Our leash is like 2 feet long, so that you almost have to bend over to keep from picking him up with it.
