Frequently Asked Questions

Can I share human probiotics with my cat?

Although they might have a similar task, human and animal probiotics don’t have the same formulation or concentration. As such, you never give your cat the same probiotics that you’re using.

After how long can one see results from probiotics for cats?

Just like any other prescription, don’t expect the probiotics for your cat to start working immediately. They usually can take some time to take effect on the body, but you might notice minor improvements in the first few days. For full effects, however, supplements like FortiFlora will show results after one or two weeks.

Can you give your cat prebiotics and antibiotics at the same time?

Basically, antibiotics are drugs that kill disease-causing bacteria to help stop infections. But since the substance can tell which is the good or bad bacteria, sometimes probiotics might end-up being destroyed in the process. hence, the reason it’s good to use both when managing your pet’s ailment.

Even so, you shouldn’t give your cat or dog the two at the same time as they can counteract. You’ll need to give one first, then wait for some moment to dose the other.

Final Verdict

If you’re passionate about your pet, the last thing you’d want is to see him/ her struggling to relieve himself. It can also be very uncomfortable to share the room if that friend is shooting some foul farts or uncontrollably defecating a very smelly, watery stool.

With the right cat probiotics, however, you truly can help curtail digestive issues in your cat and enhance his wellbeing.

Our article has reviewed the various products that can help you with that. We duly hope you found the solution that you were looking for.
