Why is it that some people don't have pets?

1) They Have Allergies

2) They Don't Like Animals

3) Too Much Responsibility

I. Some people are ill or disabled and cannot cope with an animal even though they would very much love to have a pet of their own.

2. The biggest reason I find is that they cannot afford them... the charges from vets fee's alone can be alarming, and if you happen to have an animal that needs special food because of allergies then the food can be very expensive for them too.
