I am sorry Sasha was not feeling well.
It is possible he was bitten or scratched in the area of the "lump" and he has an abscess. What happens is the wound closes over trapping bacteria under the skin.
read more here:
Apply almost hot, damp compresses to the affected area. That may get the abscess to burst and drain.
If, Sasha develops a fever,stops eating or the area swells, looks infected or turns hot or angry red, he should be seen for an antibiotic.
If you still have questions just press reply and I will be here for you.
Please let me know how he is doing.
I hope he feels better very soon.
Best wishes for him,
We haven't found any puncture wounds there. Is it possible for it to shrink on its own?
Thanks so much for your reply.
It can be impossible to see the initial puncture wound with the naked eye because it could just be a claw mark.
As long as Sasha is eating well and is not lethargic you can just apply the warm compresses. Do 5 minutes on and fifteen off for two hours. Then do cold compresses same duration. Repeat every 4 hours.
Continue with the one that gives him the most relief.
It may shrink on its own then.
Please let me know what happens.
Warmest best wishes,
