Scratching Is this product safe?

No, it's not safe. Please do not use it.

If your pig is scratching and you suspect mites, you need to treat with ivermectin. If it's fleas then use Advantage.

No, it is not safe. I hope you did not actually use it yet. Throw it away or return it.

Most of the things Petsmart markets to guinea pigs are not safe. Buyers beware type deal.

No, thankfully, I have not used it yet! It's really good to know - why is it not safe? In other words, how can I tell with future products?

I am pretty sure my piggie doesn't have mites. He used to have fleas or lice (not sure which) - I could see a few little, black dots crawling on him. Now, I don't see them any more (this only happened after I took him outside), but he scratches sometimes. I don't know if it's just normal scratching (her coat does look nice and smooth) or if they are just not visible now for some reason.

So, what Advantage treatment should I use? Could I just wash her? I would rather not use any chemicals at all...
