Oh! Very sad to hear about this!
You should give them a small piece of ivermectin! I used to get it from Lazada. I often give this to my cats and stray cats at the temple. So, they get better from sickness and fever! I saved the lives of a few cats at the temple with ivermectin! It’s an amazing medicine for cats and people too. It can cure stage 1/2 cancer. But you have to know the right dose for people. I used this to cure cancer in two people so far!
