1 of our 2 orphaned newborn kittens (6 days old of age) started eating less the last 12 hours. Before 3 hours I noticed his right front leg was swollen and took him to vet immediatelly. The vet said it might be broken bone or soft tissue injury but she cant tell or do anything before the kitten reaches 3 weeks. I keep the routine of feeding, cleaning + toilet. Is there anything more I should do?
