My cat Ginger is approximately 56-64 days along in her pregnancy. She hasn’t been eating as much as usual the last few days. She has been sleeping more also. Today, I noticed she has a vaginal discharge. At first it was brownish. Now it is a pale yellow and it’s the consistency of glue. Is this likely the mucus plug? I went ahead and set up a nesting box (she loves it!). It’s been a long time since I had a pregnant cat. Thank you for your advice!!
