My cat ate borax ant killer. Is it an emergency? What should I do?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 10 years and 6 months old | 11 lbs

my cat ate 1 teaspoon of borax mixed with 1 teaspoon of sugar which I had mixed to eliminate ants. It was in a small dish on the cupboard and I never thought she would eat something like that. I started giving her as much of her food as she would eat and then I mixed two capsules of activated charcoal in the food and she ate it all. No emergency vet is open now. This happened about 30 minutes ago. I'm scared. She is acting fine right now.

Borax is toxic to cats and you can see vomiting, diarrhea, stomach pain, and excessive thirst. This really does have to be checked out by a vet immediately, and emergency vets should be open all night. Please take Rocket Girl into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website.

my cat drank borax! what do i do?
Borax is toxic to cats, and while it it low on the toxicity scale, if Sweet drank some borax, it's best that she is seen by a vet now. Symptoms of borax toxicity include diarrhea and vomiting to muscle weakness and seizures, and are usually seen shortly after ingestion. I would take Sweet into an ER vet or find vet on call to see her now.

my dog ate a concoction of borax and water, used to attract and kill ants. is this deadly to him? what should i do?
Borax can be toxic to dogs if enough is ingested. It would be best to contact your vet or an ER clinic ASAP if he ate some. You can also contact the Pet Poison Helpline (there is a fee for this service) at https://www.petpoisonhelpline.com/ if you know how much he ate to see if it was a toxic amount that requires monitoring or immediate care. If you don't know the amount, seeking care in person ASAP is best.

Hello, my small shih tzu ingested borax (roughly 1-2 tablespoon). Is this harmful to him? And if so, what steps should I take?
Generally, the biggest issue that we may see with ingestion of borax is stomach upset and vomiting - so it's very possible that you may see this. In large amounts, borax can cause kidney failure in dogs, but this is uncommon and usually the result of long-term exposures rather than a single ingestion. If you're concerned, you can always opt to take Rocky to your nearest emergency vet for supportive care to help prevent any problems.

Will my dog be okay if she accidentally ate my homemade ant bait I used? The mixture had about 2 tablespoons of borax in it and the rest was made with water, syrup, and white sugar. I poured the mixture into a plastic takeout lid and it appears she h
The ingestion of small quantities of Borax can cause vomiting to occur. In large quantities it can cause kidney damage. It is difficult to know exactly how much was ingested since it was diluted in the water, therefore I would recommend having her evaluated by her veterinarian for blood work to monitor her kidney values. If these begin to elevate then it is possible she consumed enough to cause kidney damage. An anti-nausea medication will also help to decrease the nausea/vomiting associated with the Borax.

Hi, I laid out 3 ant traps that contained 5% borax in each metal container that only had holes small enough in them for ants to crawl in. 12 hours later my cat couldn't walk and the vet said he may of had a seizure and had to put him down. He was 10
I'm sorry to hear about the loss of your cat! How awful. It's very unlikely that the ant traps would have had anything at all to do this with this - borax is fairly non-toxic, and would require ingestion of a really large amount in order to cause any serious problems. Exposure to traces of it from simply being in the same area as the traps should not cause any issues at all. Again, I'm very sorry for the loss of your kitty.

What if my cat licked up some ant poison (Terro/ borax)? He's not vomiting but is lethargic.
Terro has a very low toxicity to humans and animals but if he is acting lethargic then he should be examined by a vet to determine the cause. Your vet can run blood-work, if needed, to help diagnose the problem and then determine if treatment is needed.

I need an emergency help as there is no any vet for cat in the area I'm staying right now. I am a microbiologist. My cat Allie is very sick. Symptoms she is showing; 1. Dilated pupils, 2. Vomited in the morning, 3. Feces is not okay. 4. Not eating or
I would be concerned that your cat is having a toxic or other severe reaction, or is very ill/sick and that unfortunately requires immediate medical attention by a veterinarian in person. If you do not have a vet in your area, trying to see if there is a vet nearby that you can get to would be best. If you suspect your cat got into the chemical, bathing can help remove any excess toxin still on the skin to stop it from absorbing more, as well as moving your cat to a well-ventilated area, however if she is already showing symptoms she requires immediate care.

My cat linked a Combat Ant Killing nait station (active ingredient filpronil) for about 3 seconds. Should I take her to the vet?
Because Blue only licked it so briefly, I would not rush her into a vet. You may see some drooling and frothing at mouth. I would rinse out her mouth with cool water using a syringe, and keep an eye on her. If she does start acting out of the ordinary, starts having uncoordinated movements, tremors, convulsions, or seizures, I would take her into a vet immediately.

Can borax any poison hurt dogs?
I'm assuming that you mean borax ant poison :) Borax can be toxic to dogs at very high doses, but it has a pretty wide margin of safety - a dog would need to eat quite a bit of it to cause any serious toxicity issues. Normally, if it's a case of a dog found chewing on an ant trap, they don't ingest enough borax from this to be a problem. You may see some mild GI upset, and in some cases the plastic parts of the trap can be an obstruction risk if swallowed, but normally there are no other serious problems seen. If Cami has ingested more than the contents of a single ant trap, I would be concerned since we would need to know exactly how much she ate to know if there are any toxicity concerns. In that case, it would be safest to take her to a vet right away so that vomiting can be induced and supportive care started if necessary.

I have a small kitten and he may or may not have eaten terro ant posin. He was just near it and may have licked a small amount. Online everywhere it says that’s it’s only toxic to ants not people or pets. But I want to make sure. And I cannot get to
I would recommend that you call ASPCA's poison control number. That number is 888-426-4435. There is a $65 charge, but they will be able to best advise you. Please have the label available so you can let them know the type of poison listed, and what any other potentially concerning ingredients were.
