Questions about each
Killing Kittens
What plans does Killing Kittens sell?+
Killing Kittens sets its offer as membership tiers: Full (Kitten) or Guest membership, plus X-PLUS. Full (Kitten) is the full tier and Guest is the lighter entry, with X-PLUS as the add on. Access runs through an app, so the tiers sit on one account rather than across separate services.
Do I need to verify before I can use it?+
Yes, Photo and ID required to apply is the entry condition. An application needs a photo and ID before the account goes live, so screening happens at the door rather than after a complaint. It also narrows who you can browse alongside you, since only approved applicants get in.
Sub or Dom
Is it free to use Sub or Dom?+
Yes, for the core of it. The service states Free to join, browse and match, which covers joining, browsing and matching at no charge. A paid tier exists alongside that, since Free and VIP membership sets out free and VIP membership as the two options, so the money comes later if you want the paid side.
How discreet is billing on the bank statement?+
The published position is a discreet bank statement with no sharing with a third party, as stated in Discreet bank statement; no 3rd party sharing. That is the only billing disclosure on record, and no payment processors are named, so check the descriptor on your own statement after the first charge.
