Is Ciprofloxacin (Cipro) Safe for Cats?
Why it’s a problem
Cats receiving fluoroquinolones without veterinary control risk nausea, vomiting, and diarrhea, and very high or repeated exposure has been linked to retinal damage in cats. A single tablet is more likely to cause GI upset than blindness, but the margin depends on the cat’s size. Food refusal afterward is the sign to act on.
How to keep your pet safe
Store Cipro where a cat cannot flick pills off a counter and chase them, and never self-dose a cat. Feline antibiotic choice and dose belong with a veterinarian.
Warning signs to watch for
Drooling, vomiting, diarrhea, refusal to eat, hiding, low energy; heavy or repeated exposure has been associated with dilated pupils and vision changes.
When to call the vet
Call your veterinarian or a pet poison hotline with the estimated amount. Any vomiting, appetite loss, or unusual pupil size afterward should be evaluated.
Common questions
My cat ate one Cipro tablet — is that dangerous?
One tablet typically causes nausea in a healthy adult cat, but the risk scales down with body size. Call your vet or a poison hotline to confirm whether monitoring is enough.
I read ciprofloxacin can blind cats — is that true?
Retinal damage has been reported in cats at high fluoroquinolone exposures, particularly with repeated or high doses. A single accidental tablet is far less likely to do this, but any exposure should be reported and any vision change examined urgently.
Can I give my cat my Cipro for a bladder infection?
No. Feline urinary disease needs diagnosis and a properly chosen drug, and human tablets are not dosed for cats. See your vet.
