Can Cats Eat Pickles?
By Pettings · Sources checked Nov 2, 2026
No. Keep pickles away from cats. A pickle is a cucumber that has sat in a brine of salt and vinegar, often with garlic and spices, and the brine is the problem. The ASPCA warns that excess salt can cause increased thirst and urination and abnormal electrolyte levels, along with vomiting, diarrhea and more serious signs in larger amounts. Many pickle recipes also use garlic, which the ASPCA lists as toxic to cats.
Why Pickles Are a Problem for Cats
Salt is what turns a cucumber into a pickle, and a single spear can carry a lot of it for an animal the size of a cat. The ASPCA lists vomiting, diarrhea, depression, tremors, seizures and even death among the possible effects of eating too much salt. The Merck Veterinary Manual describes salt poisoning in dogs, where signs can appear after about 2 to 3 grams of salt per kilogram of body weight, starting with vomiting within several hours and progressing to weakness, diarrhea, muscle tremors and seizures. Merck does not give figures for cats, but a cat weighs a fraction of a typical dog, so less salt goes further. Garlic is a second concern. Dill pickles, kosher dills and many homemade pickles are flavored with garlic cloves, and the Merck Veterinary Manual says cats are the species most susceptible to garlic and onion poisoning. Pickle relish, pickled onions, bread and butter pickles and fried pickles bring sugar, onion, batter or oil along with the salt. Pickle juice, sometimes sold as a drink, is concentrated brine and should never go in a cat's bowl.
Signs to Watch For
For too much salt, the ASPCA lists increased thirst and urination, vomiting, diarrhea, depression, tremors and seizures. The Merck Veterinary Manual notes that in dogs vomiting usually starts within several hours. If the pickles contained garlic or onion, Merck lists lethargy, loss of appetite, fast breathing, weakness, yellow gums and dark urine as signs of red blood cell damage, which often take a few days to show.
What to Do If Your Cat Ate Pickles
Call your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435 right away, especially if your cat drank brine or ate more than a small nibble. Do not try to make your cat vomit unless a vet tells you to; salt was once used to cause vomiting, and Merck notes that this is no longer recommended. Make fresh water available, and bring the jar so the vet can see the salt content and the other ingredients.
If your cat has a medical condition or eats a special diet, ask your veterinarian which treats fit before sharing any human food.
Common Questions
Can cats drink pickle juice?
No. Pickle juice is concentrated salt brine, and the ASPCA warns that excess salt can cause increased thirst and urination, abnormal electrolyte levels, vomiting, diarrhea, tremors and seizures. Many brines also contain garlic. If your cat drank pickle juice, call your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435 and bring the jar.
Can cats eat cucumbers instead of pickles?
Plain fresh cucumber is a different food from a pickle. A small piece of peeled, unseasoned cucumber does not carry the salt, vinegar or garlic that a pickle does. Keep the portion small and count it within the treat allowance WSAVA recommends, which is under 10 percent of a cat's daily calories. Never offer cucumber from a pickle jar or a dressed salad.
What happens if my cat licks a pickle?
A single lick of the outside of a pickle is a small amount of salt, but call your veterinarian if your cat chewed or ate any of it, or drank the brine. The ASPCA lists vomiting, diarrhea, depression, tremors and seizures as possible effects of too much salt. Garlic in many pickle brines adds a second concern, since cats are especially sensitive to it.
Are dill pickles worse for cats?
Dill pickles often carry an extra risk because they are commonly made with garlic. The ASPCA lists garlic as toxic to cats, with signs that include vomiting, red blood cell breakdown, weakness and an elevated heart rate. Combined with the salt in the brine, that makes garlic dills a clear no. Call your vet if your cat ate any.
How much salt is too much for a cat?
There is no published figure for cats in the source we checked, but cats are small, so it does not take much. The Merck Veterinary Manual reports that in dogs, signs of salt poisoning can appear after about 2 to 3 grams of salt per kilogram of body weight. Keep salty foods such as pickles, chips and deli meat away from your cat, and call your vet after any large amount.
