I just noticed Ty has a big knot on his underside. He's mostly white except for the few spots and the knot itself looks dark under there, and it feels a bit hard. He wouldn't let me poke at it much without having a bit of a fit and being huffy and running off. He was fixed like almost two months ago, so it wouldn't be a surgery issue would it? Is it some sort of abscess? I cannot call and schedule an appointment for him till Monday, and I think my wife can take him in for me since I work such long hours. Is there anything I can do at home till then? He is eating, drinking and running around acting normal should I be as freaked out as I am? I'm a bit in a panic because he's my favorite. I freak out when anything is wrong with my babies but especially Ty.
