Welcome to YT! Congratulations on your Lola .... I'm sure she is also happy that you found
her! 
My husband is constantly saying how much Toto has added to our lives ... she is our joy!!
We have noticed a few times, Toto chewing at her paws for no apparant reason. We always check for the obvious ... something on there that she is trying to get off, nails needing to be clipped, etc. If there is no visible reason for the chewing, we offer her something more appropriate to chew or I just snuggle her on my lap and give her a paw massage for each little foot!! She loves having her paws rubbed .... I have to believe that she occasionally chews on them because she is stressed! If Lola's chewing is constant and nothing is visible, I would check with the vet to make sure there is nothing physically wrong! Good luck!
