"I bought this after lots of research because my cat had an abscess from a bite, and I couldn't afford a vet visit.

I’ll definitely keep using it."

Her energy and mood have improved, and seeing her walk without pain for the first time in years has been amazing."

"We have a big dog with severe anxiety during storms and loud noises. Prescription meds did little, and even hemp chews took too long.

"This herbal antibiotic is a lifesaver for both my dog and cat. It’s easy to add to their meals, and I’m relieved it’s all-natural with no harsh chemicals. I’ve seen positive changes in minor skin and ear conditions, and now keep it on hand for basic immune support."

"After a lot of research, I took a chance on this cranberry treatment and I’m glad I did. Within two days, my cat seemed relieved, urinating normally and even playing again.
