when i first got makosi nearly 2 years ago
she jumped on top of the freezer one evening then fell off and fell in the bin
i quickly rescued her but she was limping and holding her paw up crying
she was only a baby
i was so worried
i rang emergency vet number and they told me just to let her rest and bring her in next morning
which i did do
and they gave her a painkiller injection
she was fine after that
back to normal
just keep an eye on him
let him rest
if he wants to stay on ya knee then let him at least then he will be resting
