Feline Euthanasia - Part 2: Clinical Considerations and Technical Recommendations

Whether the procedure is performed in the clinic or at home, the veterinary team should always have the cat’s mental health and physical comfort and the owner’s feelings top of mind.

Although the veterinarian should choose the site of IV administration based on skill and experience, the medial saphenous vein has some significant advantages, including clear visibility, easy accessibility, and distance from the patient’s head. If this vein is selected, the euthanasia solution should be diluted and a 25-gauge needle used for injection. If the intraperitoneal route is necessary, the drug can be injected and the cat wrapped in bedding or towels and returned to sit on the owner’s lap. This allows the owner to stroke and speak to the cat and removes the clinical nature of the experience.
  • Pay careful attention to the patient’s comfort. The cat can be wrapped in comfortable bedding with only the rear leg left exposed. Injection in this location may negate the need to use clippers, which can be distressing to the cat.
  • Bedding or soft towels may also be used to block the visual experience of the procedure for the caregiver. Owners can then be invited to come close to their beloved cat’s face to pet and comfort. Not only does this offer a sense of closeness and connection, but it may help to distract the owner from the technical process.

Confirmation of Death
Armed with a stethoscope, the veterinarian must ensure the cat is deceased following the procedure. This official pronouncement is a vital part of the procedure and provides some closure and allows owners to move from anticipatory to actual grief. At this moment, the relationship the veterinarian has with the owner should guide behavior. Owners should be reminded at this time that they made a loving and compassionate decision. Some people are comforted by a hug; others wish to be left alone with their beloved pet for a while. Care should be taken to accommodate their wishes.

The actions of the veterinarian and staff at this time will influence the client’s final memory of the cat and the experience. Gentle handling and common courtesy are key. If there is concern about the emotional state of the owners, they should be invited to stay for as long as necessary or to contact someone to be with them. Thoughtful inquiry will help provide the support they need.

Final Care and Follow-up
Long before euthanasia is imminent and before powerful emotions come into play, a discussion about aftercare of the body should take place. Final care and disposition of the body must adhere to local, state, and federal laws. If the owner wishes to bury the body at home (and home burial is allowed by law), provision of a cardboard “coffin” can be helpful. Licensed cremation services are widely available and a popular choice for cat owners. If cremation is elected, the choice of return of ashes or group cremation must be recorded and executed.

Acknowledgment of the loss of a beloved cat is greatly appreciated by most clients. Personalization is critical. Cards signed by the entire staff, ideally with a personal note from the veterinarian, can help with the grieving process. Many companies create tasteful sympathy cards and memorials. Condolences should always be sent before the invoice. A contribution in the pet’s name might be made to a designated pet memorial program, such as the Winn Feline Foundation. These foundations typically send a condolence card to the client indicating that a contribution has been made by the hospital to honor their cat.

Many grief counseling groups, therapists, and pet loss hotlines exist.8 Owners who are experiencing overwhelming grief should be told about these services. Some grief experts believe that having another pet to nurture helps to end the grieving process, and hospitals can often facilitate this. While some may see this as a betrayal of their lost cat and resist, others will welcome having a new pet to care for and an opportunity to recover from the emptiness they are feeling. In every case, a good sense of timing and respectful acknowledgment of the loss are important.

At-Home Euthanasia
An increasing number of veterinary services, ranging from nationwide franchises (eg, Pet Loss At Home, Lap of Love) to local mobile practices, offer in-home euthanasia. The growth and popularity of these unique veterinary practices reflect what many pet owners today consider valuable and important.9

Advantages
In the final moments for their beloved companion, many owners look for a more enriching, personal, and private experience for both themselves and their pet.10 Given how challenging it is to bring some cats into the clinic when they are healthy, it is easy to understand why many owners seek an alternative. The last thing they want is for their pet to experience any level of distress, anxiety, fear, or discomfort at the very end of life.

The primary advantage of at-home euthanasia is that it allows the cat to be comfortable and calm within the familiar smells, furniture, and people of its own environment. Understanding that losing their companion is as painful and difficult as losing a human family member makes at-home euthanasia a very natural and obvious choice for some pet owners.10

At-home euthanasia is as much about the own-ers’ experience as it is about the patient’s. Owners are looking for a private, ceremonial way to say a very peaceful and gentle goodbye.10 Many prefer to experience this grief in the comfort of their home. They can have as many people present as they want without being limited by the size of an exam room or grieving room. There is also flexibility in where the euthanasia is performed, be it in a favorite room or bed, outside in the yard, or on a porch.

Challenges
Even with its many benefits, veterinarians should discuss the drawbacks of at-home euthanasia with pet owners. There is the potential for the room where the euthanasia takes place to become a trigger for sadness for the owner. That visual image and memory of the loss of their companion can prompt owners into cycling through the grief stages long after the event. Additionally, because the cost of in-home euthanasia is typically 2 to 3 times higher than having the procedure performed at the clinic, it may not be an option for some families.

There can be challenges to performing at-home euthanasia for veterinarians as well. They must be able to enter the home and remain focused on the patient and caregiver. This can prove challenging if the home has distractions such as other pets, poor lighting, or tight quarters. Patients also may be fractious, which can make administering a sedative difficult. Traveling to the client’s home can also be challenging depending on weather and traffic conditions.

Finally, at-home euthanasia may bring an extra element of unpredictability. The veterinarian must be prepared if the patient does not react predictably to the sedation protocol. The best way to man-age this unexpected response is to always have a backup plan.10 As mentioned earlier, a very effective and gentle way to perform euthanasia is to start with an anesthetic induction agent to allow the patient to become unconscious, and then proceed with the intrarenal technique for the barbiturate.5,10 If the patient does not achieve an appropriate unconscious state, rendering an intrarenal injection impossible, then the veterinarian must be prepared to change techniques or give additional sedation. This means having the tools, skill, and sufficient medications needed to perform the euthanasia via an IV route.

It is also extremely helpful to have an experienced technician assist with the process and help manage the unexpected. This not only makes dealing with an aggressive patient easier, but it allows the veterinarian to focus on the patient and owner the entire time.
