) and its enclosure. 
It is more than likely G. iheringi, as that is what PetCo is selling as "Brazillian black wooly tarantulas."
how do you know the vendor is Petco?
I'm not 100% confident, but basing that this is a person who is very likely new to the hobby, and Petco very commonly sells G. iheringi or actaeon under the exact name, I just made a connection. Most people with questions like this are not getting them from reputable breeders, and likely got them at the closest big box store. Either way, the vendor isn't the important part here.iheringhi and actaeon slings and juvis look identical until acteon molts at about 4". The latter loses its brilliant red.

I fed it because i have a pet spider in my bathroom that is TINY and it eats more than 1 cricket a week. I assumed a tarantula needs to eat more because of its size. And the people at petco didnt have ajy kind of info for me this was they only TDon't trust care sheets! Better come here for information. This thread should be really helpful: http://arachnoboards.com/threads/tarantula-information-for-beginners-and-more.318718/
Having said that, the care sheet gave good advice with the amount of feeders you should feed. So, why did you give your sling 13 crickets in 3 days?
Tarantulas are opportunistic, they eat as much as they can. But the more you feed them the longer they'll fast before they moult... and this could be months or even longer.
As for the handling, it would be best if you never handled it. Handling isn't a requirement in T keeping, more importantly, your T doesn't get anything out of it execpt being stressed or even hurt. Handling poses many risks, especially if your T gets startled and bolts.
Lastly, post some pictures of your T ( whatever it is
heat lamp on top? If so, not a good idea at all.
News to me, thanks. I've never seen them in any Petco around me.
This doesn't work. It works for some animals, like certain mammals, and some but not all snakes.
It doesn't. Talk to any arachnologist, don't take our word for it.
Doesn't every happen.
Don't handle T, OR give it to someone else.
Power feeding is a term used in the reptile hobby that doesn't apply to the T world. The worst thing (that we know of) of feeding that many prey is the T stops eating as it's reached its satiety level.
Forever.
In a perfect world, sure. But this is with a beginner keeper, who wants to handle their spider. We can disagree with that all we want, but I doubt it will do much to sway them. Obesity leads to an easily punctured abdomen from a less than perfect setup, and can be much easier to rupture in the case of a fall from handling.
In a perfect world? not sure what you meant. I was speaking in reality.
It's a common thing for "experts" to do this, doesn't mean it's right. Tarantulas are very much like fish - look, don't touch pets. They benefit absolutely nothing from being handled. You brought up wanting to keep it docile, but why? If kept properly, you actually don't ever need to clean the enclosures. I've got spiders that haven't been cleaned in over a year. All you need to do with cleaning I'd pluck out the bolus when they're done eating.
Tarantulas (and most invertebrates) are very prone to dessication. That is, drying out. By adding a heat lamp, you are effectively drying out the enclosure so much that the tarantula could eventually die. All for no reason, as well. These don't need specific temperature ranges like reptiles. So long as you're comfortable in the room, then so are they.
This is a classic example of why i hate these kinds of "educational" techniques some use. Teaching people about ts by allowing them to handle, gives no education, but rather gives the new person the complete wrong impression about the animal, and about what is best for the animal.
Education on how to do something properly or safely is precisely how minds are changed....no one can stop what the op wants to do, but we can make every attempt to educate the person better....thats whats going on here, and theres nothing wrong with that.
Yes. There was a post on here about some, too. The Ts' abdomens were so obese, they couldn't lift them so they were drug around on the (inappropriate, to boot) substrate.I've not seen a T that is clinically obese, have you?
