Inflammatory Bowel Disease (IBD)

Inflammatory Bowel Disease is a condition that causes inflammation of the cat’s gastrointestinal tract.

Cats with IBD may experience weight loss, vomiting, diarrhea, and decreased appetite.


Cat seizures can be caused by conditions such as epilepsy, brain tumors, or infections. They can be distressing to witness and challenging to manage.

Quality of Life Assessment for Elderly Cats


The HHHHHMM Scale is a tool used to assess a cat’s quality of life. It stands for Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, and More (good days vs bad days).

This scale helps cat parents objectively evaluate their cat’s comfort levels and overall well-being. It’s a helpful tool, isn’t it?

Physical and Behavioral Changes to Look Out For

As a cat parent, it’s important to be observant and empathetic. Changes in behavior, appetite, grooming habits, and activity levels can indicate a decline in your cat’s quality of life.

Is your cat eating less? Has it stopped grooming itself? Is it less active than before? These changes can be subtle but are crucial indicators of your cat’s well-being.

When to Consider Euthanasia for Your Elderly Cat

Balancing Quality of Life and Suffering

Evaluating Pain and Discomfort

Pain and discomfort can significantly affect your cat’s quality of life. Is your cat in pain despite medication?

Is the misery too much? These are tough questions, but they’re important to consider when evaluating your cat’s quality of life.

Assessing Mobility and Activity Levels

A significant decrease in mobility and activity levels can indicate your cat is suffering. Is your cat less active than before?

Does it struggle with routine activities like jumping onto its favorite perch or using the litter box?

These changes can be hard to watch, but they’re crucial indicators of your cat’s quality of life.

Considering Eating and Drinking Habits

Changes in eating and drinking habits can also be a sign of suffering. Is your cat eating less or not at all?

Are they drinking more or less than usual? These changes can indicate health issues and affect your cat’s quality of life.

The Euthanasia Process for Cats

What to Expect During the Procedure

Euthanasia is a peaceful and painless process. Your vet will administer a sedative to help your cat relax, followed by a drug that gently and painlessly ends its life.

It’s a difficult moment, but it’s a final act of love to prevent further suffering.

Aftercare and Memorial Options

After euthanasia, you have several options for your cat’s aftercare, including burial, cremation, or memorialization. It’s a personal decision, and doing what feels right for you is essential.
