I am so sorry your baby is injured. You are such a good mommy and I can tell you are doing everything possible to nurse him back to health. Momo looks very rested in your pictures and that is just what is needed. Don't stress yourself too much about trying to force water. You will be going to the vet this morning and if he is dehydrated the vet can address it then. Poor baby...
Please let us know what your vet says today. I will say a prayer for both of you
