Does your daughter ever want pets?
There are things like frogs or turtles,
which are a bit easier to enjoy than
fish (for a child), but are unlikely to
cause allergies.
Yes, she would really like to have a cat, but she can't. Because of some dogs who nearly pulled their owner down to get at her when she asked to pet them and the owner lost control of them as well as our former neighbors dogs barking and snarling at her and breaking our fence, she is afraid of dogs. She is allergic to dogs anyway. So's my husband, so both of them would be miserable in the long run.
She isn't interested in reptiles or amphibians.
We had a rabbit before she was born, so we might get another one.
