Bless you for taking them in. I agree, I wish people would have I.D.Tags on the Pet. They might be Micro-Chipped. If you get a chance, take them to the Vet, or Shelter for a FREE Scan. Good luck!Alike in color, similar collars. 1 Male, 1 Female - inseparable. Very friendly, found at Greenwell State Park on Sunday 04/29. No one seemed to know whom they belonged to.. Please call/provide detailed description if you believe these are your pets! 301.247.1828
