My cat Suzie has recently developed swollen lymph nodes in one side of her neck and the back of one leg, she's still eating, drinking, and going potty like normal, playing, and she hasn't lost any weight. When I took her to the vet they gave her injections of antibiotics, the vet said her insides felt fine (no thickening) and they've continued to feel fine, she responded well to the antibiotics, the lumps going down slightly. One of my other cats now has a small swelling of one lymph node in her neck, but my vet insists she thinks it's cancer but she won't take blood until I schedule a surgery for the biopsy of one of suzie's lymph nodes. The only new thing that's happened before the swelling was I started using baking soda and a litter deodorizer in my cat boxes, I don't know if that can trigger some kind of allergic reaction of some sort? My vet said it's a possibility but extremely unlikely. I'm so confused as to what this could be and the stress and worry is killing me because I'm never getting an actual idea. They did a needle aspiration and the vet said "It looks bad, or it could look normal, I'm not sure it's hard to tell with aspirations of lymphnodes. This could be something to be concerned about or it could be totally normal for her." So again I'm left confused and worried.
