I'm a hypochondriac when it comes to myself and I'm a massive worrywart over my furkids. Especially with young kittens and puppies. I still worry over Samantha, but she's a big sturdy adult dog. These kittens are new and their immune systems aren't at full capacity... they just seem so tiny and susceptible. I hope you're right and it's just a lymph gland - I had a lump by my jaw this summer when I was fighting a horrible reaction to poison oak and it went away so maybe that's what Sushi's is. I hope. I feel sick to my stomach now.
