Midge&Panda
Adult Guinea Pig
One of my older girls has brown wee. Rosie is about 3 1/2 yrs and spayed, Pappi is 4 1/2 yrs and not spayed. Neither one of them is displaying any typical signs of a uti, there is no weight loss. In fact both of them have gained a little. They are still as active as always and eating plenty. Once I've determined which one it is they will be off to the vets but has anybody have any ideas. I am aware that sometimes when urine dries it oxidises and turns reddish-brown. The colour is present when the patches are wet. Rosie does unfortunately have a few lumps at the moment on her stomach though her vet is convinced that they are fatty rather than cancerous.
