I have an appointment with the vet in 48 hours because one of my cats has been doing the scoot after every trip to the litter box this weekend. It's been coming and going for a couple weeks so I assume her anal glads need expressed and she just can't get them to release this time. Is 48 hours to long to wait?? She's a little lethargic, still eating and drinking but not as much as usual. At what point does this become an emergency? Any advice is greatly appreciated!!!
