Pet Tracer is a excellent company with brilliant staff like Zoe who has been so helpful in helping me set up.our cats collar and station.This is the best collar we have tried for our darling cat.light weight has a light on it too you can switch on and I have been able to add our cats name tag etc onto the collar. Any issues I have had with no fault of anyone the staff have been quick to respond ,quick to help giving to time, patience and understanding and things get sorted very quickly. We are going to.have there outside aerial that will join the station indoors to give us a much better signal as our cat goes off to a farm and bushes and fields and hides if she is nervous so although it works great ,this is going to be even more amazing . Orders do not take long to arrive which is fab. It's great the station can be made mobile too so if your cat is stuck in a building etc you find your cat . Also comes with a band to stick inside if your cats neck is small .We use it for our cat ,brilliant idea .She has no problem wearing it and has a allumison band around it too. It also only takes about 2hours or so to recharge so we can easily take it off are cat on a evening as she in at night ,charge it then put it back on for next day .there are different modes you can use which affect how fast the battery is used the fast mode is definitely best We are so happy with Pet Tracer inwould definitely recommend to people looking for a tracking collar for there cat .I've tried loads before and were useless .This is great and staff are great too.
