So my Rat Lorenzo has a Tumor in his abdomen.. It is currently Sunday and I do not get paid until Thursday. He is still eating and drinking water and moving around, he sleeps more but is still his sweet loveable self. I noticed the tumor about a week ago and need to know if you think it’s worth waiting to try and have the surgery done? Or if it’s best to just put him down now without waiting? I looked it up and saw the surgery can be anywhere from $50 to $600. PLEASE HELP. He just turned a year

I'm sorry Lorenzo has a tumor. Unfortunately, rats in general, especially older rats, have a predisposition to developing tumors both benign and malignant. His prognosis depends on the type of tumor as well as its location. To determine either, he would need to be physically examined by your veterinarian and have diagnostics performed. This could include blood work, x-rays, abdominal ultrasound or a fine needle aspirate of the mass. Once you have this information, you can discuss all options with your vet. Good luck!
