Can Cats Take Doxycycline? Everything You Need to Know

Doxycycline is a tetracycline antibiotic commonly used to treat bacterial infections in humans. While it's generally safe and effective for people, the same cannot be said for cats. So, can cats take doxycycline?

No, cats should not take doxycycline.

While doxycycline may be effective in treating certain infections in humans, it can be toxic and even deadly to cats. This is primarily due to the drug's effect on a cat's digestive system.

Why Doxycycline is Toxic to Cats

• Esophageal Ulcers: Doxycycline can cause esophageal ulcers in cats. The medication can irritate the lining of the esophagus, leading to painful and potentially life-threatening ulcers.
• Reduced Appetite: Doxycycline can suppress appetite in cats, making it difficult for them to maintain a healthy weight and get the nutrients they need.
• Vomiting and Diarrhea: Doxycycline can cause vomiting and diarrhea in cats, leading to dehydration and electrolyte imbalances.
• Liver Damage: In rare cases, doxycycline can cause liver damage in cats.

Symptoms of Doxycycline Toxicity in Cats

If your cat has been exposed to doxycycline, it's important to watch for the following symptoms:

• Vomiting
• Diarrhea
• Loss of appetite
• Lethargy
• Difficulty swallowing
• Increased salivation
• Pale gums
• Jaundice

If You Suspect Doxycycline Toxicity

If you suspect your cat has ingested doxycycline, it's crucial to seek veterinary attention immediately. The sooner the cat receives treatment, the better the chances of a positive outcome.

Alternative Medications for Cats

• Amoxicillin
