Enough Followers for Online Shop?

My account has 86k followers and gets from 4-6k likes depending on how good the picture is. About 100-400 comments on each picture, once again depending on how good the picture is. It is in the cat niche, I plan on opening an amazon store with tons of cat products. Gaining 500 followers a day. Do you think it's too early to make a shop? Or is this a good time?

Thats a pretty good number of followers and active followers. This is good time to launch the shop.

Do you sell shoutouts?
I'm interested to buy one.

Do it and keep your followers active and entertained.
