My baby girl had to have emergency surgery about a month ago now. She had a pyomtra. Since surgery she has gained ALLLLLLOOOT of weight. Is this normal? I can't help but be a little paranoid because with the pyometra she put on weight as well. She has been so much more playful and happy since her surgery but she's a BIG OLE BALL OF FUZZ now --- I totally love her weight gain because she's been a tiny kitty most of her life but at the same time IM concerned. Should I be?
