My RB Starr was a sickly cat from day one. He was a Siamese Flame Point mix so he wasn't even a pure bred. He later had severe diarrhea and he was diagnosed with IBD/Colitis and he had to be on pred or else he'd have problems. The pred made him gain so much weight that his poor little body couldn't handle it and he could barely get around so I had to let him go. He was only 4 years old at the time.

My Pearl is a Lynx Point Siamese mix and even though she has Eosinophilic Granuloma Complex she's doing well. In her case she'll break out on her chin and lips unless she's on a grain free diet. She's now 5 years old and the vet said she's in excellent health.

My cat Storm who is just a DLH without any Siamese in him, has urinary problems. He had struvite crystals and blocked twice so he needed to have PU surgery. Now he has to have a lot canned food with added water to make sure that he gets enought moisture in his diet and he's also on a grain free diet and doing well.

Many cats can have urinary crystals, kidney problems, heart problems,and thyroid problems. They don't have to be pure breds or even siamese to get these horrible things.
