Boosty was the head of the cat posse in my home & i can clearly notice 2 of my 5 cats are upset.They lost a buddy as well.It just sucks that cats age so much more quickly then people.I thought i could handle this ok but i cant.When someones been with you for so many yrs (almost almost 15.5 yrs ) day & nite its really tough.We had a bond & i feel i let him down.Had i taken him to the vet when i first noticed his thinness & alot of water drinking he may be alive today.He was just so lifeless,crying & he didnt respond to me.I was not about to let him continue to suffer.His breathing was very slow.I feel so damn guilty."What if" is all i think about as well.I miss him so badly!
