Avoid giving your dog cat toys. For one thing, they are disgusting because they have kitty spit all over them. For another thing, we dogs (especially us wiener dogs) like to chew things up and cat toys can have little bells and other stupid things inside that we could choke on.
And whatever you do, DO NOT GIVE DOG TOYS TO A CAT!! They are mine! Besides, cats don’t know how to play with plastic water bottles properly.
