I have 2 cats, if I am stupid enough to let these plug ins run out I soon know about it! … I prefer these over the “other brand” as they last longer & are cheaper – meaning I can afford to leave them
running 24/7 around the house.
One of my cats is quite sensitive (can’t believe I just wrote that about a cat!!) but if anything significantly changes in her cat world routine it normally involves a vet visit – last time this happened the plug-ins had all run out along with one of her favourite humans (the one who feeds her breakfast) was away on holiday.
The cat household is generally calmer and happier with these running – who am I to mess with that?!
Amazon is the cheapest place to buy these & conveniently they are available on prime for running out emergencies!!
The only downside to these is they have a very herbal smell – however you soon get used to it (& the other big brand smells of wee in my opinion … so I know which I’d prefer to smell in my house!!)
The cats also respond better to the pet remedy plug ins as opposed to the other big brand.
We have a 3 bedroom house and have 2 of these running which seems to be adequate – one in the cats favourite room of course!
