My indoor outdoor cat, gives me great pleasure which I am sure is very good for me. He's also been bringing me lots of seed ticks which lead to a lot of physical discomfort.
He was feral when he showed up. He's outsmarted me on my Smart doggie door and when I tried to get him to use the litter box that just didn't happen. My dog needs the doggie door. He's almost 16 years old and I am pretty sure it would be catastrophic for him to lose his doggie door.
State of the art for animal protection for fleas and ticks, does not repel or kill them immediately. I guess I will bomb the house and see if that helps.
