We found out today that Oscar has mast cell cancer . Oscar suffers from allergies and they evidence themselves , when he has a flare - up , as spots on his belly . So he receives two allergy pills every day for most of the year . Each evening before putting him to bed I usually roll him over and check out his stomach to make sure he 's doing well and Friday night we found a marble - sized , hard lump where his testicles used to be ( had they not , long ago , been chopped off ) .
