Credit cards not part of bankruptcy

[Pizza]

I had a few credit cards with zero balances, Home Depot and Lowes for example.

I called Home Depot and requested my credit card info and it said I had a zero balance and 6k in available credit. When I called Lowes they said I had no available credit and a zero balance. I guess Lowes cut me off.

Do you think my Home Depot credit card survived, or is it just a matter of time before they cancel it too?

Personally, I would just cancel it, cut it up and throw it in the trash. If you were to charge anything up on it *then* they decided to to take action upon hearing of your BK, you would be stuck with debt that couldn't be discharged (probably at the default APR on top of it).
