My kitten just ate a selenium 200 mcg tablet. What should

This answer was rated:

My kitten just ate a selenium 200 mcg tablet. What should I do?

Dr. Kara :

Hello, I'm sorry to hear about your little one and I'd like to help.

Dr. Kara :

How much does your kitten weigh?

Customer:

I'm guessing 2 lbs.

Dr. Kara :

Thanks, XXXXX XXXXX you have 3% hydrogen peroxide in your home?
Give me a few minutes to figure out of she ate a toxic amount.
This was 200mcg right, not 200mg?

Customer:

Yes

Dr. Kara :

Ok, the lethal dose for cats is 1.5mg to 3mg per kilogram, and she is about a kilogram.
200 micrograms is 0.2mg, so she did not eat a lethal dose.
Let me see what side effects we may see.

Dr. Kara :

Ok, with the amount that she ingested you may see some vomiting or diarrhea, but that should be it.

Dr. Kara :

With higher doses you can see muscle tremors and a stiff gait due to effect on muscles, but she didn't eat enough and with a one time exposure she should be fine.

Customer:

You don't recommend we induce vomiting?

Dr. Kara :

If you want to be extra cautious you can, but cats are harder to make vomit and I really don't think it is going to cause her any trouble.
If you choose to induce vomiting give her 1/2 of a teaspoon or peroxide orally.
You might want to feed her a bland diet for the next couple days though.

Dr. Kara :

Feed her a mix of 2/3 boiled white rice and 1/3 boiled white chicken.

Dr. Kara :

This is very bland and easy to digest and should guard against any further gastrointestinal upset.

Customer:

Thank you so very much. We have an appointment for Thursday with the vet and he will probably answer our call soon.

Dr. Kara :

Very high chronic doses of selenium can cause neurologic signs, but again a one time dose that low shouldn't be an issue.
I'm sure they will get back to you soon.
Do you have any further questions for me?

Customer:

That's it. Really appreciate your advise.

Dr. Kara :

No problem, watch her closely just in case she is extra sensitive, but she should be fine.

Hi Judith,

I'm just following up on our conversation about Abby. How is everything going?

Abby was seen by her vet and all is well. She suffered no symptoms.


 


Thanks for your help.

Judith, thank you for giving me an update on Abby. I'm pleased to hear that she was not extra sensitive to Selenium and as such suffered no symptoms. Best of luck with your little one and please let me know if I can be of help in the future, Dr. Kara.
