Hi! My 3.5 year old male cat can be a little stinky, but lately it's been really bad. My guess is that it's his anal glands because his bowel discharge is pretty normal. What situation requires his glands to be expressed? Is random stinkage normal? He doesn't spray anymore, though he did when we first got him. He eats a chicken free diet because of allergies so sometimes he smells fishy, but this is different. Definitely a butt smell. Any info would be great, thanks!!
