My husband accidentally stepped one of Floyd's front paws two days ago and ever since then he's been hiding, which is completely different behavior for him. He won't even come out of hiding for meals and when we do see him he looks very nervous and subdued. We have both gently felt his front paws to see if he's hurting and he doesn't flinch in pain so we're thinking he's not really injured. He can still jump up on things and is walking without a limp. Is this normal behavior for this situation or should we take him to the vet? I really don't think he's injured, but it breaks my heart to see him this way, he is not the hiding type at all. We've petted and fussed over him but he's not coming out of his funk. Any suggestions?
