Thanks for thinking of him everyone.
Well Bugs is looking a bit sorry for himself this morning but hes eaten well and pooped too so thats all good.
It doesn't look to me like the lump has gotten bigger overnight (although his eye is still half closed)so maybe theres no further collection of pus but I won't count on that just yet.
He'll start antibiotics this morning and hes back at the vets tomorrow afternoon ....fingers crossed it doesn't grow during today because that abcess came up so quickly I couldn't believe it.
