It
is okay for me to let my cat roam outside.
If you do a search we've had this debate before and somewhat recently. I feel no need to support my decision to let my cat be a free-roaming inside/outside cat.
You may feel the suggestion should not be made, fine, don't make it. I feel otherwise and shall do with my opinion what I'd like.
And if you didn't want to start a debate, you wouldn't have said anything to begin with...if we want to play with semantics.
That's a great idea. You may need to condition the cats to it if they are not already comfortable with it. If money were not an option they have enclosures that cats can go into and be kept in their own yard. That's not feasible for many, though.
It may just be a trick of buying different toys to see what your cat likes.
Go to a dollar store! That's a great place to start. Good luck!
