Hiya everyone just posting this message as i have some concern for my cat, misty. Shes 66days into pregnancy and showing many signs however last night i think she started contractions, her back flinched rapidly and from then on her back tightened for about 30 secs then loosened this happened for about ten minutes and then stopped she hasn't had anything else since, could anyone tell me if these are contractions or if i have anything to worry about, any help at all would mean alot, thank you, sadie
