I have a 1 1/2year old female great dane name Meridell. after a place that saved my life

my first cat named tiger who is brother to the cat we still have and SHE is 12 years old. died when I was in 5th grade. he got water crystalls stuck in his urinary tract, we are still paying for vet bills
and like I said-his sister (Jazz, purty, pretty kitty) is still alive and doing well

after tiger died, on my birthday my mom got me a kitten from an animal shelter. she is a silver tabby. I named her starrlet. then called star, now called fatso. she reminds me of a dog. comes when I wistle, will eat anyhting
our puppy (stewie) was born may 31st. we got him at 6 weeks old.
