I live in california and this summer is already scathingly hot. I'm concerned about the health of my cat with regards to the temperatures here. I supply him with lots of cool water and shady places but should I keep him inside all day to play it safe?
What about cat door?
don't have one
Make sure he drinks a couple of times day. If he's not inclined to drink water, give him wet cat food. It's better than being dehydrated.
The water thing is your best bet
