living with a senior cat

Fon is 8 years old now which is old for a Maine Coon. She is still big and fluffy but she sleep 18 hours a day and doesnt jump on the fridge like before. Thor (the Siamese) is young and very loud so I think they are good for each other, like a grandma and a teenager. Thor has to be gentle with her or Fon will just leave the room. For her food I switch to the senior wet food from the pet shop near Pinklao market and add some water so she can drink more. Her teeth are not good anymore, I have to brush every day, she hate it but she let me. Vet says ask for blood test every 6 month now. I think I will do it in May. Also my mom says she needs a warm blanket in the winter, which is not really winter in Bangkok lol but ok.
