Hi there Aria! We are more than happy to help you out with this issue!
It seems your cat just needs a little 'texture refresh' of sorts. To do this, you will need to put the cat in and out of low prim mode.
To put in and out of low prim mode : Touch Cat > Prims > Low Prim > 2D Cat, Then Low Prim Off. This will correct the leg texture issue.
We have a manual full of all sorts of information as well that might be of use to you here: https://kittycats.ws/manual/
You can also always file a Support Ticket and ask us about any issues here: https://kittycats.ws/support/index.php?/ticket/submit-ticket
I would also like to take a moment to remind everyone of our Community Standards. Keep things friendly and to contact people privately if there is an issue, or contact staff directly if there is an issue.
Please remember to respond kindly to each other and be helpful to everyone. If you are unable to do either of those things, then it is best to not respond at all. If you see a post that does not fit with our Community Standards, then please contact a member of the staff and let us know so we can look into things.
Thank you all!
