Hi there,
I am so sorry your cat was hurt. Unfortunately he cannot take any human OTCs as most are toxic to cats.
You can apply compresses - alternate warm and cold - 5 minutes on and 5 off and see which gives him more relief.
Keep him indoors with as much rest as possible.
Please let me know how he is doing. I will be here late if you need me.
Best wishes for him,
Terri
