The most common symptoms of constipation in cats include not defecating for several days, frequent visits to the litter box without defecating, screaming during defecation, hard stools with blood, etc. Probiotics cannot solve constipation in cats. Regularly giving cat-specific probiotics can help regulate the cat's gut flora, improve the digestive system, and effectively prevent constipation. However, if a cat is already constipated, probiotics alone will not cure it. If a cat is constipated, it needs to be taken to a veterinary clinic for treatment and medication. 
What are the causes and solutions for constipation in cats?
1. Dietary issues. If the food the owner feeds the cat is too dry or too oily, or if the owner frequently changes the cat food or buys cat food that is of poor quality or too cheap, it can lead to constipation in the cat. Therefore, owners should pay special attention to their cat's diet, choose high-quality cat food, and ensure that there is plenty of clean drinking water.
2. Insufficient exercise in cats. Because owners are often busy with work, they have less time to play with their cats, resulting in insufficient exercise. Owners may not realize that their cats eat a lot but don't exercise enough to digest, which can lead to constipation. Therefore, owners should remember to take their cats out for walks or play with them more often.
3. Overeating. Cats that eat too much at once may experience indigestion or gastroenteritis, which can also lead to constipation. Owners should spend more time with their cats and gently massage their bellies, give them more yogurt or honey water, and consider adding some probiotics like Guden cat probiotics to promote intestinal motility and help them defecate more quickly.
4. Hairballs. When a cat has too many hairballs in its body and cannot expel them smoothly on its own, constipation will occur. Therefore, the owner needs to supplement the cat with hairball remedy or cat grass in time to help the cat expel the hairballs and restore the cat to a healthy state.
