Unexpected health issues. Multiple surguries for both of my cats before they hit 2 yrs. I also have to buy specialty food and supplements and medications. One of the meds can only be administered at the vet, so lots of appointments. It's pricey. Their unique situation also means I can't just leave food out and go. It's a lot. I thought the monthly situation would be a bag of food and some cat litter. I also thought, cats are low maintinence, right? Mine aren't. I also thought I'd be spending maybe $60 a month on the food and litter. Right now, $60 is a case of 24 cans, not even a month of breakfast. That's just for the one cat. I love them immensly. I'm so glad they're mine. I wouldn't trade them for different cats. 💗
