My cockatiel tootoo (about 3 years old) started behaving a little bit abnormally today. He pees a lot and gets puffed up more frequently than other days. His droppings seem to be normal and whenever he pees clear liquid comes out. Other than those two symptoms nothing else seems to be off. He is pretty active, eats normally and sings like every other day. there has been no changes in his diet and the house is always at a constant, high enough temperature. Sadly for us avian vets dont work at weekends so i cannot take him to the vet till Monday. i'm quite worried and i'd like to know if anyone knows what could case those symptoms and what could i do to help him during the weekend. Thanks for your time.
