Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. It is difficult to say for sure what is going on without examining her myself. Based on your description, you say she may be in heat, yet the Pet's info section it states that she is unspayed. If she is not spayed, she could be dealing with something called a pyometra, which is when the uterus fills with pus. This can be a life threatening condition. I would strongly recommend having her examined by a veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. Please refrain from giving any antibiotics until you have spoken with a veterinarian that has examined her. I hope this helps!

Sally needs to see a vet ASAP. Her signs of excessive drinking, vomiting, and inappetence after going into heat make me highly concerned that she has developed a pyometra, which is a life-threatening uterine infection. These infections typically occur about 2 weeks after a heat cycle due to hormone fluctuations and cause the uterus to become distended and filled with pus. If left untreated, a closed pyometra can cause the uterus to rupture in the abdomen and causes sepsis (a systemic bacterial infection). I understand your concern about finances. Consider looking into Care Credit (carecredit.com) which offers financing for veterinary procedures. Many SPCAs and local shelters have low cost veterinary clinics, but Sally really needs to be seen by an ER now.

Poor Maisie. It's not normal that she has lost weight and has had some bouts with vomiting. Without seeing her in person, I can't say for certain what is going on, but one concern I would have is a pyometra. This is an infection of the uterus that is fatal without treatment and can cause the symptoms you are seeing. I think it would be best if you take her into a vet immediately to get checked out. The vet can do blood work, urinalysis, and possibly an abdominal x-ray to see what is going on with her. If she does have a pyometra, spaying her is part of the recommended treatment. I hope this helps!
