ALL OF JENNYS PETS ARE DOGS EXCEPT ONHE. HOW MANY CATS AND DOGS DOES JENNY HAVE,
There is not enough information to answer the question. You also need to say if the "other pet" is a cat.
If so, there is one cat. The number of dogs can be any number larger than zero.
To determine the number of cats and dogs Jenny has, we need more information. The given statement tells us that all of Jenny's pets are dogs except for one. However, it doesn't specify how many pets Jenny has in total. Without knowing the total number of pets, it is not possible to determine the exact number of cats and dogs Jenny has.
If you have access to additional information, such as the total number of pets Jenny has or any other details, please provide that information so we can assist you further.
