Blood Test for Cats

Blood Tests for Cats

Nobody enjoys having their blood taken, but there are many benefits that outweigh the minor discomfort of blood testing. Cats have the disadvantage of not being able to tell us if something is wrong. Their instinct is to hide it from us instead. Blood testing in combination with regular check-ups is a great way to screen for any problems that may be arising.

Why are blood tests important for my cat’s health?

Blood tests are important for your cat’s health, as cats are very good at hiding their diseases. Routine blood testing can catch a disease early, which can help control or slow down a disease process. The most common diseases that we find in cats include kidney disease, hyperthyroidism, and diabetes. When running routine blood tests, these diseases can be detected before symptoms are noticed. For example, once clinical signs are seen for kidney disease, there is at least 75% damage to the kidneys already.

How long does it take to get blood test results?

We have many options for blood testing. Often, we send our wellness blood tests to an external lab, where we receive results the following business day. For pre-anesthetic blood testing, emergencies, and some monitoring tests, we can run them in-clinic and have results within an hour.

How should I prepare my cat for their blood tests?

There isn’t any ‘prep work’ for cats. If it is a specialty test (something other than a wellness blood test), please call the clinic for instructions.

How often should blood tests be done?

Studies report that one year for a cat is about four years for us. Therefore, we would recommend running routine blood tests yearly. If abnormalities are found, we would recommend running blood tests more frequently and advise you as to how often.

Does your clinic perform urinalysis?

We perform both urinalysis and biopsies here. Urine can be difficult to collect from a cat. Some people have found just using clean empty litterbox works, others use a non-absorbent product, such as NoSorb (for cats that need something to dig in the litterbox), while others require a cystocentesis (a sterile procedure is done in-clinic to collect urine). Urine is best run as fresh as possible and no more than 4 hours old.

Being a Veterinary Technician

October was Veterinary Technician Month, though many of us feel that it could be a year-round celebration.

Dear Clients,

As Ontario continues its reopening, we are excited to see our community get closer to a sense of normalcy. We applaud the significant effort and sacrifices you and your family have made to help us get this far.


At Manitou Animal Hospital our primary goal is to care for your beloved pets. By extension, this means keeping you as a pet parent healthy as well. Many of you have already recently visited the hospital and have personally experienced the additional safety procedures we have put in place to ensure the well-being of you and your pets using our “closed waiting room” policy.

Our "closed waiting room" policy:

  1. When you arrive in the parking lot, please remain outside the hospital and use your cell phone to call 519-893-1360. We will take a history of your pet's health and discuss any concerns.
  2. A staff member will then meet you outside to bring your pet into the hospital for an examination.
    We ask that you remain in the parking lot and keep your phone turned on.
  3. The Veterinarian will call you once the physical exam is complete to discuss the recommended treatment plan.
  4. We encourage credit card over the phone as the preferred payment method. We can also accept e-transfer.
  5. A staff member will bring your pet and any medications back outside to you.

During the coming months and as long as COVID-19 continues to circulate in our community we at Manitou will continue to offer our services using these enhanced safety procedures, including the curbside and closed waiting room service model. For the health and safety of everyone, we will not be able to have you accompany your pet(s) into the clinic for procedures at this time. We unfortunately would just not be able to meet proper physical distancing requirements and ensure your safety and our team's.

We typically have a significant number of clients [100+] visit our clinic daily whether it be for medication, food or for a visit with the veterinarian or vet technician. Space in the front room and the exam rooms is very small, a well documented factor for increased risk of COVID transmission. If everyone were to come inside our clinic, even with masks on, it would significantly increase the risk of COVID exposure to each client entering the clinic as well as our staff. We are simply not willing to risk the health of you, your family and our staff. We know that with continued effort we will get through this together. We sincerely appreciate your patience and help in working with us during these challenging times.

Until then, we promise to give each and every one of your pets the very best care and a ton of hugs and kisses when they are in for a visit. We always treat them as if they were one of our own and look forward to seeing them!
