An enlarged spleen can be felt by any non-professional. It will feel like a slightly stiff hamburger patty curving around & slightly folded in the tummy. Most especially, you can feel the edge of it for a few inches. Enlarged spleens are nothing to worry about unless they're lumpy or so big that it's pushing other organs out of place (& that diagnosis is for a vet to make!). Think of the spleen as a biological trash can, rounding up leftover infection remnants & system toxins that you never have to empty because the more trash that's chunked in it, the bigger it gets (which an EXTREME oversimplification, for a technical definition and those who have time, ask Bob Church. LOL). The small grape is a worrisome thing, though. If it feels like there's a small grape (anything from 1/4" diameter up and not squishy like a water balloon - which is how the bladder feels) just hanging around loose in the abdomen could be a cancer of some type. I'd definitely get to a vet for a qualified diagnosis on this one. Debi Christy Ferrets First Foster Home [Posted in FML issue 3157]
