So because I let my cats outside I am not a responsible pet owner? I am always amazed at the cultural differences between the UK and the USA, considering we have a common language, there are still many cultural differences between the two countries. Cat ownership seems to be one of them. Here in the UK it is considered normal to let your cats outside and it is actually considered cruel to have indoor cats, it is the belief that cats are naturally outdoor creatures and all vets I have used over the years agree with this. I know many cat owners and all allow their cats outside. Out of my friends we all have cat flaps so the cats can come and go as they please, we all regularly take our cats to the vets for their injections and worming tablets, our cats are all microchipped, spayed and we are all responsible pet owners. I have 2 cats (both healthy 11 year olds). They can go out into the street if they want to, but they usually choose not to. My cats stick to their patch, our garden, next doors garden and the one next to that where they are welcome. I know they are welcome there as the house owners have said so, next door even keep their door open during the day when we are at work and the cats keep them company (they are a retired couple.) Maybe the differences are due to other wildlife in the two countries, here where I live there are no animals who are a threat to them. But suggesting that I am not a caring and responsible pet owner for allowing my cats outside is to me actually quite insulting.
