I have an inside squirrel I’ve had since 2 days old she’s an Eastern Gray she’s now 6 months old. She acted “different” about 2 months ago and I took her to the vet.. he said he couldn’t see anything in her urine that it may just be behavioral. Since then she has acted perfectly normal but her tail hair seems to be falling out. No chewing no injury. First it was about an inch down from the tip but today I notice she’s thinning right away under her tail close to the base. I’ve removed all the scary foods corn peanuts avocado human food..we are just having healthy block (a little daily she hates them) two tablespoons of fox valley formula bok choy kale insects and so forth. Could it be stress
