Update Post #6; URI UTI, and that's just the start.
Took 3 pets - 1/4 of the family - to the vet this morning: Vita, Sparkle and Sugar.
Vita has a URI for sure. She has been urinating around the house, so may have a UTI as well. She has lost a pound in weight since May, I hadn't noticed as she has all the long fur. She is on Clavamox for 10 days. Will have urinalysis results on Friday afternoon. The vet suggested she is urinating due to stress, as she is always using a vertical surface.
Sparkle went in because she is losing weight and has added a feeding every 24 hours. She has lost almost 3 pounds since May. She had blood work and urinalysis, results will be in Friday.
Sugar (dog) has a sinus infection and is on Clavamox. She is wheezing both inhaling and exhaling. No problem with her lungs, it is all in the sinuses, and probably some post nasal drip. The NOISE keeps the whole house awake at night.
$455 later, we all trouped home again.
