Cat is 5 months and is very very small for his age. Hasn’t grown since 2 months. He was born with slightly flat ribs and his lower end is flat which made him not walk when he was little but I trained him to walk and he can walk now. He started to sleep constantly and barely keep himself awake. He eats fine but isn’t drinking water unless I put his hard food into his water. His fur has gotten raggity and looks like dandruff filled in his fur. He can barely stand up yet alone walk. He wobbled and falls to only his right side. Checked his legs nothing is wrong. His hind legs are weak. He will fall face into the ground and slowly fall over. His 3rd eyelid has been showing a lot. He will lean on food bowl to keep himself up to eat. He won’t use his tongue and never has b4 that’s why I put food and his water in the same bowl. His ears are cold even if I warm them up. Hind legs seem to be going inactive like when he was first born
