No documented August 2026 change altered feline-constipation guidance, approved a new treatment, or identified a constipation outbreak. Feline constipation—the infrequent or difficult passage of hard, dry feces—still warrants veterinary attention when signs persist. The month's closest cat-health development was a kitten milk-replacer recall, not a constipation update. A separate FDA adverse-event listing included one constipation report involving Solensia, but it does not prove the medication caused the problem.

What actually changed in August?
On august 26, the FDA posted Revival Animal Health's voluntary recall of certain Shelter's Choice and Breeder's Edge feline milk replacers. Testing found low levels of potassium, copper, folic acid, choline, vitamin B6, or a combination of these nutrients, according to the FDA recall notice.
The affected products reached customers nationwide through online sellers and retail pet stores. This makes the recall relevant to kitten caregivers across the country, but it does not represent a change in constipation treatment. Anyone using these products should:.
- Compare the package with the lots listed in the recall notice.
- Stop feeding a recalled lot.
- Seek veterinary advice if a kitten develops clinical signs.
Is the milk-replacer recall linked to constipation?
The available evidence does not establish constipation as an outcome of the recalled products. Revival reported no confirmed illnesses while investigating nine complaints involving possible gastrointestinal or bone-development problems. Gastrointestinal complaints cover a broad category, so they should not be treated as confirmed constipation cases.
The recall identifies inconsistent nutrient levels as the reason for action, not a constipation cluster. The risk matters most for neonatal kittens. Their rapid growth and complete reliance on milk can make nutrient deficiencies apparent within days or weeks, with potentially fatal or permanent effects, as explained in the FDA and Revival Animal Health announcement.
What does the Solensia report mean?
An FDA adverse-event listing printed July 14, 2026, recorded one voluntary constipation report involving Solensia through March 31, 2026. That entry is a safety signal for review, not evidence of cause.
The FDA warns that voluntary reports cannot establish causation or calculate how often an event occurs. Underlying illness, other medications, incomplete reports, and unknown exposure totals can all affect the data, according to the FDA's July 2026 adverse-event listing.
What should cat owners watch next?
The established clinical picture remains unchanged. Cornell lists fur, foreign-body obstruction, tumors or strictures, electrolyte or neuromuscular disease, and medication effects among the possible contributors to constipation in cats in its feline constipation guidance. Owners should watch for infrequent or difficult passage of hard, dry feces.
These signs do not identify the cause, so assuming the problem is simply food-related can delay an appropriate assessment. Persistent constipation deserves veterinary evaluation rather than unsupervised treatment. Severe cases that do not respond can progress to obstipation or megacolon.
