Bladder Infection in Cats

Both dogs and cats get bladder infection and though not unique to one breed, the short leg, heavy muscle build of certain breeds can increase the tendency to get bladder issues. In dogs, females are more prone than males because of their short urethra. In cats, male cats are especially prone to bladder infection because of the position of the prepuce below the rectum. If they have bladder issues, they need to be treated before sandy stones form a plug that prevents urinating.


Early signs of Urinary Tract Infection (UTI) start as excess licking of the genital area progressing to burning then frequent trips to the litter box but urinating little. UTI will cause squatting for an extended period of time due to bladder spasm infection and stones irritating the urethra. As the infection and spasms progress, small amounts of blood may be seen in the urine.


With bladder infection, urine becomes more alkaline (like baking soda) and sandy stones tend to form. This sand can harbor bacteria that cannot be killed by antibiotic as antibiotic cannot get into the crevices of the stone. The bacteria can then set up housekeeping after the antibiotic is removed, reestablishing the UTI. Eliminating bacteria and sand where bacteria hide will eliminate the bladder spasm that causes discomfort!


  1. Antibiotic to take care of the infection
  2. Urinary acidifier Cranberry and Potassium Citrate to remove stones. The acid urine gives the pet two advantages in fighting UTI:
    • Pulls and holds antibiotic in the urine where it is more effective rather than in the blood where it wants to stay.
    • The mild acid environment is soothing to bladder tissue and making urine unfavorable for bacterial growth and stone formation.


If you have a breed that is prone to bladder infection, it is best to prevent before the burning and sand or stones happens. Once bladder infection is cleared, maintain bladder health with Doc Roy's­ Potassium Citrate + Cranberry at one half the treatment dose. By creating an unfavorable environment for bacteria and stone formation we can control the bladder infections our pets have to endure.

Prevention is always preferred to treatment and a lot more comfortable!
