Why Shouldn’t Cats Get Caffeine?

Cats should not consume caffeine because it can be toxic and cause several adverse effects. Caffeine is a stimulant that affects the central nervous system and can cause restlessness, rapid breathing, and muscle tremors in cats. 

Large amounts can lead to severe symptoms such as high blood pressure, abnormal heart rhythm, and death. If you suspect your cat has consumed caffeine, contact your veterinarian immediately.

How Much Caffeine Is in Green Tea?

The amount of caffeine in green tea can vary depending on several factors, such as the type of green tea.

Green tea contains less caffeine than tea made from fully fermented tea leaves. However, it still contains caffeine, ranging from 30 to 50 milligrams per 8-ounce serving. 

It’s important to note that humans’ recommended daily caffeine intake is 400 milligrams. However, cats have a much lower tolerance for caffeine and can be sensitive to even small amounts.

For this reason, it’s vital to ensure that the green tea you give to your cat is decaffeinated.
