Hello!
Thank you for rescuing!
Kittens bring both the joy of watching a life come to life and the conundrum of not really knowing for sure what is simply a problem due to neglect and what might be a longer term issue that needs medical resolution.
In my experience almost all of these guys resolve their issues on their own with just simple basic tlc and time. So I wouldn’t worry about this until time and patience decides otherwise.
I would diligently treat the ear for dirt, mites abs possible infection and follow up with the vet as indicated.
Cross each bridge as you get to them and not before. Kittens will amaze you every time.
Good luck.
Keep us posted.
Hello,
Usually these are just scar tissue between the body wall and skin. If you have a regular vet ask them to check for you. Just in case. If you don’t have one it’s a good idea to establish yourself as a client so that you have someone who knows you when you need routine care or even the occasional mishap/illness needs.
