just noticed my cat whimpers when I picked him up today and forgot about then later that day I picked him up and he did it again. It's seems to be when I tuck his tail and back legs in my arms when he does it. But did it when my husband cradled him like a baby he whimpered too. He ate his dinner, no vomiting, or anything. He has been weeing and so on like normal. He is very quiet and when I pat him down his back he usually lifts his tail but he isn't. We have no money to take him to the vet. He walking slower too. He is 3years old and had him for just over a year. When he walks his tail is down even when am giving him food. What could it be?
