Hello. My cat (cwtchy) had her four kittens just over 24 hours ago. I knew she was in labour so I changed her cat litter and it clearly hasn't been used since. Is this normal? She's eating and drinking fine. Thanks in advance :(

Keep an eye on her to make sure she is continuing to eat/drink and nursing and caring for the litter. As a new mother the stress of labor and taking on a litter of kittens may just have her devoting all her energy to the new kittens. If she's still eating she should have a bowel movement within the next 24 hours.
