It seems to be very hard on all the outdoor cats this year...we have 4 that have adopted us,2 have been a abandoned by arab families who used to live on our compound,and 2 youngsters,probably born here. One desperately wants to be inside but our dogs won't tolerate him.he comes in for a cool down daily while the dogs are shut away safely. 6/7 years isn't old though...we've had quite a few who have lived in good health to 18 years of age! I'm sorry I can't help you either,I know what it's like to see them suffering in this heat,I find it quite upsetting to be honest! All I can do is feed them and put plenty of water out for them,at least that way,I know they are well fed and watered!
