Staci, I had to stop giving Phoenix treats when he had urinary crystals.
It was very hard on me at first, having to listen to his whining and begging.
I stopped buying treats all together and after a while he got used to it.
I try to compensate with catnip and also play with him more.
My cats are seniors and don’t play as much as they did when they were younger, but there is one game that makes them act like kittens again: Wiggle a peacock feather under a few sheets of newspaper.
Or you could adopt a playmate for Kylie.
