The following information isn’t intended to replace regular visits to your veterinarian. If you think your cat may have feline infectious peritonitis, please see your veterinarian immediately. And remember, please do not give any medication to your pet without talking to your veterinarian first.
Here are some reasons your cat might drool too much, along with suggested treatments.
Mouth disease and tooth decay. Tartar buildup can rub on the inside of your cat’s lip, causing her to slobber. To check, pull her lip back toward her ear. Do her teeth look like concrete? Are they brown? Are the gums red, swollen, or even bleeding?
Try a professional cleaning first, and then brush her teeth daily. Have your vet check for gingivitis, mouth ulcers, and tumors.
Trouble swallowing: While playing, a string or a toy might get stuck in your cat’s mouth or wrapped around her tongue. Try to remove the object yourself, or call your vet for help.
Then again, your cat might have a hard time swallowing just because she has a bad taste in her mouth. Maybe she didn’t quite swallow her medicine, or she licked or ate something gross. Just keep an eye on her to make sure she stays out of trouble.
Heatstroke: Pets with flat faces, such as Persian cats, are more likely to have heatstroke. It isn’t as common in cats as it is in other animals, though, because felines have less fur. Still, if your cat's had too much sun or not enough water, that's dangerous for her.
Always have fresh, clean water available. Make sure your cat has shady places to cool off, too. On very hot days, keep her indoors, limit her exercise, and never leave her in a parked car. Call your vet right way if you suspect heatstroke.
Motion sickness: Cats don’t usually take car rides -- unless they’re going to the vet for shots. Those trips could be bad memories for her, making her nervous or nauseated.
Open-mouth panting and breathing, signs of anxiety, can cause your cat to drool. To make her more comfortable, you can try putting her in her carrier in the back seat without driving anywhere. Then, slowly work up to backing out of the driveway and driving around the block. Gradually repeat the routine as needed to ease carsickness.
