Hello there....my cat Piper is VERY pregnant. I took her to the vet on 3/4/21 and they did an ultrasound and estimated that she was maybe 45 days. I totally know that was an estimate but she still has not gone into labor. She is not acting sick or like anything is wrong, she is getting bigger and bigger. She eats a ton and sleeps a ton. I cannot see movement but she is a smaller cat. Any tips or things I should check as this is my first time with a pregnant cat. Thank you all in advance
