My kitten needs all her shots the cost?

You pay only the cost of the vax. Would depend on which or how many. You will not pay less anywhere else for sure.

I took my cat there 3 weeks ago and the shots cost $40..exam is free, but suggested donation is $20.

Gail, U only pay for the shots that ur kitty needs. The visit is free and the shots are also at a discounted price. There is a donations box on the wall in their office, there is not a required donation amount but donations are recommended to help run/support the clinic. I love Merwin's, my family has been going there since I was a little girl. I was 12 when we brought our 1st pet there, I am now 36 yrs/o I highly recommend arriving as early as possible being this is a 1st come 1st served situation. I can guarantee U that U will not find a cheaper price for ur kittens shots/visit. Best of luck with ur new Kitty

Just costs of shots and A donation is welcome too but not mandatory.
