I am so nervous my cat, Buttercup, is 3 years old and this morning I found a brown stain on my bed. My mom and dad think she has a urine infection and we have an appointment with the vet at 1:30 today. I am just so nervous is anyone here a vet or has had a cat that has had this before???? She is very healthy otherwise and this is the first time I have seen a brown stain on my bed or anywhere. Please reply with any info you might have.
