hi all

I have a mate who loves chipmunks, he has a bunch of them and houses them in an outdoor aviary. He has neighbours pet cats coming in his garden and passing his aviary and lurking around it, and spraying around it and other things in his garden
Like me he is a keen wildlife lover and wants birds and other wildlife to keep going in there too
He doesnt use the internet anymore so i got the idea to ask on here to see what other people say and if you have any knowledge
Hes has tried loads of deterrents but none have worked, some working for a really short time before becoming useless. Hes come across a product called `Cat Watch` which is apparently the only motion detector which has been tested and approved by the RSPB. Hes interested in getting it but is afraid of the frequencies affecting his chippies. Ive read in books and online of chipmunks being affected by frequencies from televisions and radios. Getting that product is like the last resort as he has already tried lots of deterents and spent money on them to try and deter them. Hes thinking of putting it in his garden to try and scare them off from coming in, and the product is said to be really effective. The product is supposedly that cats can only be affected by it, and it has been approved by the RSPB so it doesnt affect birds, i wouldent imagine
I wanted to find out for him if you can have one of those motion sensor things in your garden when you house chipmunks in the garden? Will it affect the chipmunks or will they not be effected by it?
