We're hoping to go on a holiday after New Year (Covid allowing!) - but slightly worried about our 2 cats as we only ever left them for 1-2 nights so far. We have a cat sitter coming twice a day when we're away, but because the cats are veryshy, the won't come out while she's here - they are still eating and using a litter tray as normal once she's left, but I'm worried they may get really bored dung the week we're away so can anyone recommend any interactive toys/home made solutions to get cats entertained without human presence? They are litter siblings, 1 year old and indoor only. Both are very active and currently we would play with them for approx. 1.5 hours per day. They love chasing wands and snack hunts but don't particularly enjoy playing with anything by themselves (we tried crinkle balls/ping pong balls/catnip mice and fish toys etc). Many thanks!
