My cat is on Oncovin. How do I keep other pets safe and handle waste?

My cat is taking Oncovin. They said to be careful around saliva. Does his wet nose count? If he drops a piece of food and another cat eats it (happens from time to time) will the others be ok? What’s the benefit of double bagging if stuff is already in the trash?

There is not very much drug residue in the saliva, but we normally recommend against allowing an animal receiving the drug to lick you. I would not worry about a normal wet nose. They have not studied the effect of the drug on other cats in the house, but I would discourage Chester from licking the other cat and may consider keeping them separated if Chester grooms the other cat a lot, but a bite of food woudn't be enough to concern me. There is more drug residue in the urine and stool, so that would be a larger concern. Here is the reference in a drug handbook for this drug. "On the day your animal gets the drug and then for a few days afterward, all bodily waste (urine, feces, litter), blood, or vomit should only be handled while wearing disposable gloves. Seal the waste in a plastic bag and then place both the bag and gloves in with the regular trash." The reason for the double bagging is to have a back up if one bag gets a hole in it and to make sure that the first bag is sealed. I hope that was helpful and answered your questions. Thanks for using Petco Pet Education Center, formerly Petcoach.
